What is the equator? What does the equator mean?

The equator refers to the longest circumferential line in the trajectory of each point on the earth's surface with the earth's rotation. Its radius is 6378.2 kilometers and its circumference is 40075.02 kilometers ... The equator is the dividing line between the southern hemisphere and the northern hemisphere. It divides the earth into two hemispheres, the northern hemisphere is in the north and the southern hemisphere is in the south, which is the baseline for dividing latitude. The equatorial latitude is 0, which is the longest latitude on the earth. At the same time, the equator is the place with the smallest acceleration of gravity on the earth.

What continents do the equator cross?

The continents crossed by the equator are South America, Africa, Asia and Oceania in turn.

1, South America

South America is the abbreviation of South Asia and America, located in the western hemisphere and the southern hemisphere. It borders the Atlantic Ocean in the east, the Pacific Ocean in the west and the Caribbean Sea in the north. North America and North America are bounded by the Panama Canal, while South America and Antarctica face each other across the Drake Strait.

2. Africa

Africa, the full name of Africa, is located in the western part of the Eastern Hemisphere, south of Europe, west of Asia, east of the Indian Ocean and west of the Atlantic Ocean, spanning the north and south of the equator, covering an area of about 30.2 million square kilometers.

3. Asia

Asia, alias "Asia Asia", is the largest and most populous of the seven continents. It covers 8.7% of the total area of the earth.

4. Oceania

Oceania, with a total land area of about 8.97 million square kilometers, accounting for about 6% of the world's total land area, is the smallest continent in the world. It is the least populated continent in the world except Antarctica. It is located in the vast sea area north and south of the equator in the central and south-central Pacific Ocean.

Equatorial landform climate

The equator is a low-pressure area, and the northeast trade winds and southeast trade winds blowing from both sides of the equator drive the seawater on both sides of the equator to flow from east to west. It is called the North Equatorial Warm Current in the north and the South Equatorial Warm Current in the south.

When the equatorial warm current reaches the west coast of the ocean, it is blocked by the land, and a small part of it turns eastward, forming an equatorial countercurrent; Most of them flow to higher latitudes along the coast under the action of geostrophic bias, and the west wind drift is formed by westerly winds in the middle latitudes. When it reaches the east coast of the ocean, part of it turns to the low latitude of the west coast of the mainland and becomes the compensation current of the equatorial warm current; The other part bends to high latitudes along the west coast of the mainland, forming a polar circulation.
