The Pacific Ocean is the largest, deepest, and most marginal sea in the world's oceans. The ocean with the most islands. According to more information, it was first discovered and named by the Spanish explorer Basco. The word "Taiping" means "peace". In the 16th century, the Spanish navigator Magellan entered the Pacific from the Atlantic through the Strait of Magellan and arrived in the Philippines. During the voyage, the weather was clear and the waves were calm, so he named this sea area "Pacific". The Pacific Ocean is located between Asia, Oceania, America and Antarctica. The Bering Sea Strait at the north end is connected to the Arctic Ocean, to Antarctica in the south, and to the Atlantic and Indian Oceans to form the waters surrounding the Antarctic continent. The maximum length of the Pacific Ocean from north to south is about 15,900 kilometers, and the maximum width from east to west is about 109,900 kilometers. The total area is 178.68 million square kilometers, accounting for one-third of the earth's surface area and one-half of the world's ocean area. The average depth is 3957 meters and the maximum depth is 11034 meters. There are 6 trenches over 10,000 meters in the world, all concentrated in the Pacific Ocean. The Pacific Ocean has a seawater capacity of 707.1 million cubic kilometers, ranking first among the world's oceans. The Pacific Ocean contains very rich resources, especially fisheries, aquatic products and mineral resources. Its fish catch, as well as the reserves and grade of polymetallic nodules, rank first among all oceans in the world.

Atlantic Ocean

The Atlantic Ocean is the second largest ocean in the world. It is located between South and North America, Europe, Africa and Antarctica, running north to south, like an "S" shaped ocean belt. It is about 15,000 kilometers long from north to south and narrow from east to west. Its maximum width is 2,800 kilometers. The total area is approximately 91.66 million square kilometers, which is slightly more than half the area of ​​the Pacific Ocean. The average depth is 3626 meters, and the deepest point is 9219 meters, located in the Puerto Rico Trench. The ocean is rich in resources and rich in fish, accounting for more than one-fifth of the world's catch. Maritime transportation in the Atlantic is particularly developed. The east and west communicate with the Indian Ocean and the Pacific via the Suez Canal and the Panama Canal respectively. Its freight volume accounts for more than two-thirds of the world's total freight volume.

Indian Ocean

The Indian Ocean is the third largest ocean in the world. Located between Asia, Oceania, Africa and Antarctica.

It covers an area of ​​approximately 76.17 million square kilometers, with an average depth of 3,397 meters, and the maximum depth of the Java Trench reaches 7,450 meters. There are ridges running roughly north-south in the middle of the ocean floor. Most of it is in the tropics, with an average water surface temperature of 20°C to 27°C. Its marginal sea, the Red Sea, is the saltiest sea in the world.

Ocean resources are the richest in oil, and the Persian Gulf is the world's largest submarine oil producing area. The Indian Ocean is the world's earliest navigation center, and its waterways were the first to be discovered and developed in the world. It is an important channel connecting Africa, Asia and Oceania. Ocean freight volume accounts for more than 10% of the world's total, with oil transportation ranking first.

Arctic Ocean

The Arctic Ocean is located in the northernmost part of the earth, roughly centered on the North Pole, between Asia, Europe and the northern coast of North America. It is the smallest in area and volume among the four oceans. The shallowest ocean. The area is about 14.79 million square kilometers, accounting for only 3.6% of the world's ocean area; the volume is 16.98 million cubic kilometers, accounting for only 1.2% of the world's ocean volume; the average depth is 1,300 meters, only one-third of the average depth of the world's oceans. The maximum depth is only 5449 meters. The Arctic Ocean is the coldest frigid ocean among the four oceans. It is covered with snow all year round and is covered with ice for thousands of miles. The solid ice covering the ocean is 3 to 4 meters thick. Whenever the sea water here flows southward into the Atlantic Ocean, clusters of huge icebergs can be seen floating with the waves and drifting away, like some terrifying monsters, which has brought certain challenges to human shipping industry. threaten. Moreover, there are two major wonders in the Arctic Ocean. The first wonder is that for almost half of the year, there is continuous darkness, just like the long night with no sunlight; while for the other half of the year, the sun shines mostly, with only day and no night. Because of this, a day and night in the Arctic Ocean seem to be one day instead of one year. In addition, when you are in the ocean, you can often see the aurora phenomenon in the Arctic sky, which is erratic, ever-changing, colorful, and very beautiful. This is the second largest wonder in the Arctic Ocean.

Its population is 3.229 billion, accounting for approximately 60% of the world’s total population, ranking first in the world.

Africa: Covering an area of ​​approximately 30 million square kilometers, accounting for approximately 20.2% of the world’s total land area, it is the world’s second largest continent. ***There are 56 countries and regions. The population is 662 million, accounting for 12.3% of the world's total population, ranking third in the world.

North America: Covering an area of ​​approximately 24 million square kilometers, accounting for approximately 16.2% of the world’s total land area, it is the third largest continent in the world. ***There are 37 countries and regions. It has a population of 432 million, accounting for approximately 8.1% of the world's total population, ranking fourth in the world.

South America: Covering an area of ​​approximately 18 million square kilometers, accounting for approximately 12% of the world’s total land area, it is the fourth largest continent in the world. ***There are 13 countries and regions. It has a population of 302 million, accounting for approximately 5.6% of the world's total population, ranking fifth in the world.
