The earth is the third and fifth largest planet from the sun: orbital radius:149,600,000 km (from the sun 1.00 astronomical unit); Planet diameter:12756.3km; Mass: 5.9736e24 kg Earth is the only name that doesn't come from Greek or Roman gods.

The word earth comes from old English and Germanic. Of course, there are many other languages.

In Roman mythology, the goddess of the earth was called Tellus- fertile land (Greek: Gaia, Haiya, Mother Earth). It was not until the Copernican era of16th century that people realized that the earth was just a planet. Of course, the earth can be observed without flying machines, but we didn't have a map of the whole earth until the twentieth century.

Photographs of the earth taken in space are of great value; They are of great help to weather forecast and storm tracking forecast. And these pictures are very nice! The earth is divided into different strata (depth-km) due to different chemical composition and seismic properties: 0-40 crust, 2700-2890 D'' layer -D "layer, 40- 400 upper mantle-upper mantle, 2890-5 150 outer core-400- 650 transition reg. Ion-transition zone 5 150-6378 inner core-inner core 650-2700 lower mantle-lower mantle crust thickness is different, which is thinner in the ocean and thicker below the mainland.

The core and crust are entities; The outer core and mantle are fluids. Different layers are separated by discontinuous sections which are obtained from seismic data. One of the most famous is the Moho surface between the crust and the upper mantle.

Most of the mass of the earth is concentrated in the mantle, and most of the rest is in the core; We live in a small part of the whole (the following values are * 10E24kg): atmosphere = 0.000005 1 ocean = 0.00 14 crust = 0.026 mantle = 4.043 outer core = 1.835 inner core = 0. The temperature in the center of the earth's core may be as high as 7500K, which is hotter than the surface of the sun. The lower mantle may be composed of silicon, magnesium, oxygen and some iron, calcium and aluminum. The upper mantle is mainly composed of olivine, pyroxene (iron/magnesium silicate), calcium and aluminum.

These are all through seismic technology (the so-called seismic technology refers to the method of artificially creating a seismic source on the surface, such as a bomb, and understanding the underground structure by receiving underground echoes); We can only get samples of the upper mantle in magma, but we can't do anything about other layers. The crust is mainly composed of quartz (silica) and other feldspar-like silicates.

Generally speaking, the chemical elements of the earth are: iron 34.6%, oxygen 29.5%, silicon 15.2%, magnesium 12.7%, nickel 2.4%, sulfur 1.9% and titanium 0.05%. The earth is the densest star in the solar system. Other terrestrial planets may have similar structures and material compositions, but there are also some differences: the moon has at least one small core; Mercury has an oversized core (relative to its diameter); The mantle of Mars and the moon is much thicker; The moon and mercury may not have a crust composed of different chemical elements; The earth may be the only earth-like planet with an inner core and an outer core.

It is worth noting that our theory about the internal structure of planets only applies to the earth. Unlike other terrestrial planets, the earth's crust consists of several solid plates, each of which floats on the hot mantle.

It is called plate theory in theory. It is described as having two processes: expansion and contraction.

When the two plates move away from each other and the magma below forms a new crust, it will expand. Shrinkage occurs when two plates collide with each other, and the edge of one plate extends below the other plate and is destroyed by heat in the hot mantle.

There are many faults at the plate boundary (such as the San Andreas fault in California), and there are also collisions between continental plates (such as the Indian Ocean plate and the Eurasian plate). At present, there are eight plates: North America plate-North America, Northwest Atlantic and Greenland-South America plate-South America and Southwest Atlantic-Antarctica and its coast-Eurasian plate-Northeast Atlantic, Eurasia except India-Africa, Southeast Atlantic and West Indian Ocean-India and Australia plate. Most of Australia and the Indian Ocean (Nazca Plate)-the East Pacific Ocean and the parts adjacent to South America (Pacific Plate)-most of the Pacific Ocean (and the south coast of California) and more than 20 small plates, such as the Philippine Plate.

Earthquakes often occur at the junction of these plates. The surface of the earth is very young.

In a short period of 500 million years (astronomical standard), the process of erosion and tectonic movement has been repeated, and most of the earth's surface has been formed and destroyed again and again, thus removing most of the original geographical traces (such as craters caused by the impact of stars). In this way, the early history of the earth was cleared.

The earth has existed for 4.5 to 4.6 billion years, but the oldest known stones are only 4 billion years old, and there are only a handful of stones over 3 billion years old. The earliest biological fossils are less than 3.9 billion years old.

There is no exact record of the moment when life really begins. 0% of the earth's surface is covered with water.

The earth is the only planet that can have liquid water on its surface (although there are liquid ethane and methane on Titan's surface, and there is also liquid water underground on Europa). We know that liquid water is an important condition for life.

The heat capacity of the ocean is also an important condition to keep the earth's temperature relatively stable. Liquid water has also caused surface erosion and continental climate diversification, which is a unique process in the solar system (it may have happened on Mars a long time ago).

The earth's atmosphere is composed of 77% nitrogen, 2 1% oxygen and trace amounts of argon, carbon dioxide and water. When the earth was first formed, there may be a lot of carbon dioxide in the atmosphere, but almost all of it is combined into carbonate rocks, and a small part is dissolved in the ocean or consumed by living plants.

At present, plate tectonics and biological activities maintain the cycle of carbon dioxide. A small amount of stable carbon dioxide in the atmosphere is of great significance to maintain the surface temperature through the greenhouse effect.

The greenhouse effect has increased the average surface temperature by 35 degrees Celsius (from -2 1 Celsius in freezing to14C in human). Without it, the ocean will freeze and life will be impossible. From a chemical point of view, the existence of a large amount of oxygen is very obvious.

Oxygen is a very active gas, which generally reacts easily with other substances.

Asia is the abbreviation of "Asia Asia". The word "Asia Asia" comes from the Semitic language of the ancients in ancient West Asia and other places. Asia means the place where the sun rises in the east. Asia is home to China, India and Babylon, which are ancient civilizations in the world. It is also a place where Buddhism, Christianity and Christianity are relatively developed, which has a great influence on the development of world culture. Asia is located in the northeast of the Old Hemisphere, bordering the Pacific Ocean in the east. The Atlantic Ocean in the west belongs to the Mediterranean Sea and the Black Sea. The mainland stretches from Cape Yezhnev in the east (west longitude 169 degrees 40 minutes, north latitude 60 degrees 5 minutes), to Cape Pai in the south (east longitude 103 degrees 30 minutes, north latitude 17 minutes), and to Cape Baba in the west (26 degrees 3 minutes, north latitude 39 minutes). 77 degrees 43 minutes north latitude). It spans the widest latitude of all continents, covering almost all climatic zones and natural zones from the equator to the North Pole. It also spans the widest longitude, and the time difference between east and west reaches 1 1 hour. The northwest is bordered by Urals, ural river, Caspian Sea, Caucasus Mountains, Bosporus Strait and Da Daniil Strait. The Suez Canal is separated from the southwest, and the Red Sea is adjacent to Africa. Southeast and Oceania across the sea; The Bering Strait, which is only 86 kilometers wide in the northeast, is opposite to North America. Asia covers an area of 44 million square kilometers (including islands), accounting for 29.4% of the world's total land area, and is the largest continent in the world. The Asian continent is adjacent to the European continent, forming the world's largest land mass-Eurasia, with a total area of about 50765438+100000 square kilometers, of which the Asian continent accounts for about 4/5. Residents: Especially in South Asia. Yellow race (also known as Mongolian race) is the main race, accounting for about 60% of the population of the whole mainland. The rest are white, brown and mixed-race. There are about 1000 nationalities and races in the whole continent, accounting for about half of the total number of nationalities and races in the world. Among them, there are more than one billion Han people and only a few hundred nationalities or tribes. The inhabitants of Asia belong to Sino-Tibetan language family, South Asian language family, Altai language family, Korean language family and Japanese language family. ), Malay-Polynesian language family, Dalopi tea language family, Semite-Hermite language family, Indo-European language family, etc. Asia is the birthplace of Buddhism, Christianity and Christianity. Natural environment: The coastline of the Asian continent is long and tortuous. The coastline is 69,900 kilometers long. It is the longest continent in the world. Coastal types are complex. There are many peninsulas and islands. It is the largest peninsula in the world. Kalimantan island is the third largest island in the world. The overall feature of Asia's topography is that the surface fluctuates greatly, with mountains, plateaus and hills accounting for about 3/4 of the whole continent. The average elevation of the whole continent is 950 meters. Apart from Antarctica, it is the highest continent in the world. The whole continent is roughly centered on the Pamirs, and a series of tall mountains extend in all directions, the highest of which is the Himalayas. There are many vast plateaus and basins between high mountains. Beyond mountains and plateaus, there are vast plains. There are many famous peaks in Asia, and the peaks over 8,000 meters in the world are distributed in the Karakorum Mountains and the Himalayas. Among them, Mount Everest, the highest peak in the world, is 8848 meters above sea level. Asia has the lowest depressions and lakes in the world-the Dead Sea (the lake is 592 meters below the Mediterranean sea level), and the Qinghai-Tibet Plateau, which is called the roof of the world. Asia has the most volcanoes in the world. The islands around the eastern edge have the most volcanoes in the world. Earthquakes are frequent in eastern coastal islands, Central Asia and northern West Asia. Many rivers in Asia originate in the central mountainous areas and flow into the Pacific Ocean and the Pacific Ocean respectively. Followed by the Yellow River, 5464 kilometers long; The Mekong River is 4500 kilometers long. The longest inland river is the Syr Darya River, followed by the Amu Darya River and Tarim River. Lake Baikal is the largest freshwater lake in Asia and the deepest lake in the world.

The northern coastal areas have a cold tundra climate. Most parts of Siberia belong to temperate coniferous forest climate. The mid-latitude area near the Pacific Ocean to the east belongs to it. Transition to subtropical forest climate in the south. Southeast Asia and South Asia have a savanna climate, and most of them have a rainforest climate near the equator. Most parts of Central Asia and West Asia have desert and grassland climate. The Mediterranean coast of West Asia has a subtropical Mediterranean climate, and the extreme minimum temperatures in Egor Sk and Oymyakon in eastern Siberia reach -7 1 Celsius, which is the lowest temperature in the northern hemisphere.

Geographical handwritten newspaper materials

In the late period of burning Huluyu and Cyclone Three Kingdoms, Zhuge Liang made a northern expedition to the Central Plains and visited Qishan Mountain six times.

Sima Yi and Wei Jun were once trapped in Huluyu. There are fires all over the mountain, trying to burn all the enemies to death.

Sima and his son couldn't escape this fate, crying to die. Unexpectedly, a sudden heavy rain doused the mountain fire, and Sima survived.

In fact, the rain was not "providence", but Zhuge Liang himself. The raging fire caused the air near the mountain area to heat up and the air pressure to decrease.

Cyclone is formed in the low pressure area, and it rains in the center due to the rising, cooling and condensation of air. That is to say, there was cyclone rainfall in Huluyu.

Although Zhuge Liang is familiar with astronomy and geography, he lacks modern scientific knowledge and doesn't know what a cyclone is. Otherwise, he may use other tactics to destroy Wei Jun. On the eve of Battle of Red Cliffs, due to the east wind and monsoon, Zhou Yu sent troops to fight against Huang Gai.

Offering a series of stratagems to set Cao Jun on fire, I suddenly remembered that I had neglected a major event and was very ill.

Zhuge Liang took the opportunity of visiting the sick to point out that Zhou Yu's illness was "only caused by the east wind" and promised to borrow the east wind to help him. Why does Zhou Yu "owe" Dongfeng? Because the ancient battlefield of Chibi lies in the monsoon region of eastern China.

It was the middle of winter, the northwest wind prevailed, and the southeast wind rarely blew. Cao Ying is in Jiangbei and Soochow is in Jiangnan. Attacking with fire will burn your home.

Zhou Yu's anxiety is reasonable and in line with the climate law. The so-called "borrowing from the east wind" is actually Zhuge Liang's prediction of short-term weather anomalies around winter, which is just a mystery.

Concepts such as monsoon, climate and weather can be naturally derived from this story. Ancient Greek Legend There is a legend in ancient Greece: A long time ago, Hector Rivaz, the sun god, had ten sons.

Four sons, Mercury, Venus, Earth and Mars, are small and thin, but very filial. They always follow their father and the sun god loves them very much. Ai Dong, Jupiter and Saturn are fat, kind-hearted and fond of making friends, but the sun god is not satisfied with these three sons.

The other three sons were named Uranus, Neptune and Pluto. These three brothers don't talk or laugh all day, and they are gloomy and indifferent. The sun god hates them a little. They dare not go near their father. They always stay away from the sun god.

One day, encouraged by a friend, Fa Ai Dong drove his father's Japanese car out to play. Because of his poor driving skills, he almost burned a Japanese car and was chopped to death by Zeus with lightning. Ai Dong was attached to his father and brother and didn't want to stay away from them, so his flesh and bones became thousands of small pieces. These small pieces were called asteroids, sandwiched between the orbits of Mars and Jupiter, and revolved around the sun god forever.

Gulf War and Natural Belt In the invasion war and the Gulf War, the United States played the trump card of air force, but the result was the opposite. Apart from political reasons, the difference in natural environment between the two places is a very important reason. Vietnam is located in the tropical monsoon rainforest belt. Along the "Ho Chi Minh Trail", the forest covers the sky and the rugged mountain terrain makes it difficult to observe the military dynamics on the ground from the air.

It is not conducive to the us military to complete its intentions.

I drew the contents of the geography manuscript about the global climate, and I went to draw the manuscript after graduating from junior high school geography.

Global climate refers to the global distribution of climatic elements (temperature, pressure, wind and precipitation, etc.). ) and its seasonal changes. For example, the global temperature distribution is characterized by the decrease of temperature with the increase of latitude. The lowest temperature in winter in the northern hemisphere is below -40℃, the highest temperature is 25℃, and the temperature difference between north and south is 65℃. The lowest temperature in summer is about 0℃ (Sahara desert). The temperature difference between north and south is only 40℃. In winter, the continental temperature is lower than the average temperature at the same latitude, while the ocean is the opposite. In summer, the situation is just the opposite. The basic characteristics of sea level pressure distribution are: high latitude is low pressure area, subtropical zone is high pressure area, middle latitude is strong meridional pressure gradient area, and isobars are dense. There are three main zonal wind zones in the northern and southern hemispheres, namely tropical trade winds (easterly belts). The precipitation in the mid-latitude area is more than that in the subtropical area, especially in the cyclone active area, and the annual precipitation can reach1000 mm. The formation of climate types is due to the different combination of heat and water, or the different seasonal distribution of water, or the existence of huge mountains and plateaus, some of which still have certain differences in the climate within the same climate zone, which can be further divided into several climate types. For example, different atmospheric circulation conditions are all in the same subtropical climate zone. The east coast of Eurasia is monsoon climate type, and the west coast is Mediterranean climate type. Second, the main climate types 1) Tropical climate (1) Equatorial (tropical) rainforest climate is roughly distributed between 10 latitude, mainly distributed in the Amazon River basin in South America, the Congo River basin in Africa, the Gulf of Guinea, the southwest coast of Indian Peninsula in Asia, the Malay Peninsula and the west coast of zhina Peninsula in India. Philippine Islands and New Guinea (also known as Irian Island), from Oceania to New Guinea and Sumatra Island. The annual temperature difference is very small, and the annual precipitation generally exceeds 2000 mm, and the distribution is relatively uniform. Natural vegetation is a tropical rainforest plant. (2) The tropical grassland climate is roughly distributed between the north and south latitudes 10 and the Tropic of Cancer. This is typical of Central Africa, South America and most of Brazil, northern and eastern Australia. This kind of distribution area is located in the alternate control area of equatorial low pressure area and trade wind area. The annual temperature is high, with an average annual temperature of about 25℃. During the control period of equatorial low pressure area, equatorial air mass prevailed and precipitation was concentrated. The trade wind control period, controlled by tropical continental air mass, is dry and rainy, and is divided into dry season and wet season. The annual precipitation is generally 700- 1000 mm, with an obvious and long dry season. Natural vegetation is tropical sparse grassland. (3) Tropical desert (arid and semi-arid) climate (1) The tropical arid climate is generally distributed on the mainland and the west coast under the control of the north-south regression high pressure zone. Take North Africa, Asian Peninsula and Australian desert as typical examples. Controlled by subtropical high pressure zone or trade wind zone, and controlled by tropical continental air mass all the year round. Downflow prevails, with drought and little rain. The annual precipitation is about 100mm, and in some places it is only a few tens of millimeters or even less. There is plenty of sunshine and high temperature. The average temperature in the hottest month can reach about 30℃. The contradiction between heat and water is prominent. The world is very big. It is closely related to the tropical dry climate. The natural vegetation is desert. (2) The tropical semi-arid climate is distributed at the outer edge of the tropical dry climate zone. Its main characteristics are: first, the rainy season is short, and the annual precipitation can be increased to 500mm；; Second, the temperature on the high latitude side is not as high as that on the low latitude side. (4) The tropical monsoon climate is generally distributed on the east coast of the mainland between the north latitude 10 and the tropic of Capricorn, with Indo-China Peninsula, Indian Peninsula and other places in Asia affected by the southwest monsoon as typical examples. Most parts of Yunnan, southeast corner of China and other places also belong to tropical monsoon climate. The annual temperature is high, and the annual average temperature exceeds 20℃. A windy season. In the winter half year, under the control of tropical continental air mass, precipitation in some places decreased obviously, forming a dry season. The annual precipitation 1500-2000mm, and the rainy season accounts for more than 80-90% of the annual total. The natural vegetation is tropical monsoon forest. 2) Subtropical climate (5) Subtropical monsoon climate and subtropical monsoon humid climate (65,438+0). Taking the eastern part of Asian continent, such as south of Huaihe River in Qinling Mountains of China, southeast of North America, east of South America, southeast of Australia and southeast corner of Africa as typical examples, the prevailing wind direction has obvious seasonal changes. In winter, affected by the polar continental air mass, the temperature is low and the precipitation is low. In summer, affected by tropical ocean air mass, it is hot and rainy, and the seasonal distribution of water is uneven. The natural vegetation is subtropical evergreen broad-leaved forest (the obvious reason for East Asia is that it is backed by the largest continent and faces the largest ocean, and the thermal properties of land and ocean are significantly different). (2) The subtropical monsoon humid climate is distributed in southeastern North America, eastern Argentina in South America and southeastern Australia. In these areas, there is also a considerable amount of precipitation in winter, and there is little difference between winter and summer. Therefore, it is called subtropical monsoon humid climate. Climate is also caused by the difference of thermal properties between land and sea, but the difference of thermal properties between land and sea in this climate distribution area is not as strong as the former, and the precipitation is more than the former. (6) The subtropical Mediterranean climate is mainly distributed on the west coast of subtropical continent, such as the Mediterranean coast, the west coast of the continent with latitude of 30-40 in North and South America, the southwest corner of Australia and the African continent, with the Mediterranean coast being the most extensive and typical. Take the northern hemisphere as an example. In winter, the subtropical high zone moves southward, which is warm and rainy under the influence of the westerly belt (Mediterranean front belt). Natural vegetation is evergreen broad-leaved forest and evergreen shrub. (7) Subtropical desert (arid and semi-arid) climate (1) Subtropical arid climate is mainly distributed in the western mainland and inland areas of 25 ~ 35 south latitude, and its basic characteristics are similar to those of tropical desert climate. However, due to the high latitude, the winter temperature is lower than the tropical desert climate. (2) The subtropical semi-arid climate is distributed at the outer edge of the sub-tropical arid climate zone, with little rain all year round. The main difference from the subtropical arid climate is that the summer temperature is lower, and the average temperature in the hottest month is lower than 30℃. The annual precipitation is more than 250mm, so the soil water storage capacity increases, which can maintain the growth of grass. (8) Subtropical.
