What does it mean to run through the north and south?

Question 1: What is the line that runs through the North and South Poles called? The Earth's axis is the Earth's oblique axis, also known as the Earth's rotation axis. It refers to the axis around which the Earth rotates. The northern point of intersection with the surface is the North Pole, and the southern point of intersection with the surface is the South Pole.

In geology, there is another type that refers to the axis of the earth's structural units, such as the Kangdian axis, the Inner Mongolia axis, etc. The term "earth axis" was proposed by Huang Jiqing (1945), who placed it on the edge of the platform in my country. The long-term uplift composed of basement metamorphic rock series is spread in the shape of a long axis, and the area with strong activity is called the earth's axis. It is a secondary structural unit of the quasi-platform, such as the Kangdian axis, the Inner Mongolia axis, etc. The characteristics of the Earth's axis are: ① It is often accompanied by an axis-edge depression on the side of the Earth's axis toward the platform; ② The side where the Earth's axis and the geosyncline are adjacent is often bounded by deep faults; ③ There are multiple cycles of orogeny and magmatic activity, which constitute multiple It is a cycle tectonic magmatic activity zone and therefore also a multi-cycle mineralization zone.

Cause of tilt

No matter where the earth is in its orbit, its north pole is always facing the North Pole, and the same is true for the south pole. According to Newton's law of universal gravitation, there may be a star above or below it. Earth's South Pole or North Pole.

Earth's axis hypothesis

①The Earth's axis is the imaginary axis of the earth's rotation. The Earth is constantly revolving around this imaginary axis. Therefore, it is also called the earth's rotation axis. This axis passes through the center of the earth and connects the north and south poles. The angle with the earth's orbital plane is 66°34'. The Earth's axis faces Polaris. The plane passing through the center of the earth and perpendicular to the earth's axis is called the equatorial plane.

The position of the earth's axis in the earth is not fixed, but moves slightly, causing "polar shift". Its extension line is the "celestial axis". The two intersection points of the Earth's axis and the ground are the "Earth's poles". The two intersection points of the celestial axis and the celestial sphere are the "celestial poles".

② The geological axis of the earth is located in the linear uplift zone at the edge of the platform. It is a relatively active secondary structural unit in the forward direction within the platform. The term "earth axis" was proposed by Chinese geologist Huang Jiqing in 1945. The fold base is widely exposed, and the sedimentary cover is missing or underdeveloped. Faults and magmatic activities are relatively strong, endogenous minerals are also abundant, and the caprock folds are gentle. The earth's axis is often the boundary between two sedimentary areas with different properties, such as the Inner Mongolia axis and the Qinling axis in China.

Impact of earthquakes

The northeastern coast of Japan was recently hit by a major earthquake that had not been seen in thousands of years. Scientists said that this earthquake was so powerful that the entire earth was moved by 25 centimeters. In addition, the massive earthquake changed the Earth's rotation rate, causing changes in the length of the day. Experts from Italy's National Institute of Geophysics and Volcanology said that the energy released by Japan's 9.0-magnitude earthquake was astonishing. It moved the earth's axis by 25 centimeters, changed the earth's rotation speed, and had a slight impact on the length of the day and the season. Influence. But in fact, for the huge earth, this change is very small. Andrew Meier, a professor at the University of Toronto, said: "If you look at the ruler in front of you, 25 centimeters may seem very long. But in front of the entire Earth, 25 centimeters is very small. This movement will change the length of the day and will also change the tilt of the Earth. It affects the length of the season, but these effects will be very, very small.”

Daniel McNamara, a seismologist with the US Geological Survey, said that this disaster is still possible due to the huge cracks in the seafloor. Changed Japan's coastline, moving Honshu Island 2.4 meters. He also warned that the earthquake also caused part of Japan's territory to sink, and that much land will permanently sink below sea level. "We have seen many underwater cities in the past, and that is the result of sinking." Experts from the University of Tokyo's Seismological Research Institute and the University of Tsukuba say an earthquake of this magnitude may occur only once every thousand years. It is likely to trigger more earthquakes, so greater vigilance is necessary and Tokyo residents should be prepared for larger earthquakes to strike.

Question 2: What is the Grand Canal that runs from north to south? The Beijing-Hangzhou Canal was originally built by Emperor Yang of the Sui Dynasty, but its original location was from Beijing to Luoyang and then to Hangzhou. It was transformed into a modern appearance in the Yuan Dynasty.

Question 3: As shown in the figure, the reason why ③④ can penetrate the north and south is that B. the central part of the continent is low and flat

The cold air from the Arctic Ocean can drive southward through the central plain; from the tropical Atlantic The humid air blowing can also penetrate deep into the north through the central plains, so the climate in North America is very unstable. Winters are sometimes cold and sometimes thawing. Severe cold and snow can also occur in the subtropical areas along the Gulf of Mexico in winter.

Question 4: Running through the north and south ① Passing through; connecting: this highway ~ more than a dozen counties in this province. ② Running through: the spirit of unity and mutual help ~ in our entire workshop.

North and South : south, north

The meaning of "through the north and south": from south to north, unobstructed

Question 5: This railway runs through the north and south of our country. What does "through" mean? "Book of Han? Biography of Sima Qian": He also has a wide range of readers, running through the classics and biographies, galloping through ancient and modern times. , refers to penetration, Jiang Fan's "Han Xue Shi Cheng Ji? Zhu Shenghe": Sun Xingyan, courtesy name Boyuan, has read more than ten thousand volumes, and his exegesis, geography, and the study of yin and yang and the five elements are endlessly connected (through).

Question 6: According to Baidu, the meaning of north-south transparency is as follows: The so-called north-south transparency means that the living room runs through the north and the south. This house is your living room + dining room, and both are considered north and south. Transparent. North-south transparency is a broad concept. In the north, it faces the sun from the south and has windows to the north and south. In the south, it faces the sun from the north and has windows to the north and south, both of which are transparent from the north to the south. There is no specific conclusion on the concept of Feng Shui. Xuankong Feixing and Big and Small Xuankong each have their own opinions. Some use the window as the sitting direction, and some use the entrance door to determine the sitting direction. Therefore, there is no need for you to worry about north-south transparency. From your description, your room type is very good because it has good lighting and ventilation. Hand-made, I hope you will adopt it!

Question 7: What does the north-south transparency of a house mean? North-south transparency. First of all, the house must be oriented north-south, and then there must be balconies or windows in the north-south direction, so that the air can directly cross each other and people can live in it. Nice and cool. To achieve the effect of north-south transparency, formal plate structures can generally achieve this effect, and individual end rooms with dish-type structures may also achieve this effect.

Question 8: What does a house with transparency from north to south mean? Is this room type good? Attached picture~~~~ The so-called north-south transparency means that the living room runs through the north and south. This house is your living room + dining room, which are connected together, and there are windows in the north and south, so it is called north-south transparency.

This kind of house type is considered to be a popular house type now. It is the same as our house type. It is called: Wuming, which means that all five houses have windows. It is brighter to live in. In summer, it is ventilated from the north to the south and the air flow is better. Good, the layout is also relatively reasonable, and the design of directly leaving the wardrobe space in the two bedrooms is very practical. But I don’t know the area of ​​the specific house type. The bathroom of this type of house usually appears smaller. If you like a large bathroom, you can deal with it during decoration.

Question 9: When was China’s north-south railway built? In 1876, the first railway appeared on Chinese soil. This was the Wusong Railway built by the British capital group through deception. This railway was in operation for more than a year before it was demolished by the Qing Dynasty. Five years later, under the auspices of the Westernization faction of the Qing Dynasty, the construction of the Tangshan-Xugezhuang Railway began in 1881, thus marking the beginning of China's independent railway construction. Later, railways from Taipei to Keelung Port and to Hsinchu were built in Taiwan. However, due to the ignorance and isolation policy of the Qing Dynasty, there was great resistance to the construction of railways in the early days. By 1894, on the eve of the Sino-Japanese Sino-Japanese War of 1894-1894, only about 400 kilometers of railways had been built in the past two decades.
