What are the five continents and the seven oceans?

Five continents: Asia, Europe, Africa, America and Oceania.

Seven oceans: North Pacific, South Pacific, North Atlantic, South Atlantic, Indian Ocean, Arctic Ocean and Antarctic samples.

People often say that there are five continents and four oceans, which are the general names of the four oceans on the earth (Pacific Ocean, Atlantic Ocean, Indian Ocean and Arctic Ocean). It also refers to all the oceans on the earth. The ocean area is 36 1 10,000 square kilometers, of which the Pacific Ocean accounts for 49.8%, the Atlantic Ocean for 26%, the Indian Ocean for 20% and the Arctic Ocean for 4.2%.

The reason for the difference: the continent is made up of light and hard silicon and aluminum, floating on a heavy and sticky layer of silicon and magnesium, just like ice floating on the water. Before Carboniferous, there was only one continent (Pangea) and one ocean (Pangea) in the world. Under the action of tidal force and centrifugal force, since Mesozoic, Pangu land has been gradually fractured and separated, resulting in polarization drift and westward drift. Continental drift and submarine expansion have caused the present situation.

Northern and Southern Hemisphere (the continental boundary between the seven continents and the four oceans)

1, northern and southern hemispheres (equator)?

2. East and West Hemisphere (20 W,160 E)?

3. Asia and Africa (Suez Canal)?

4. Asia and Europe (Urals, ural river, Caspian Sea, Caucasus, Black Sea, Turkish Strait, Note: Russia belongs to Europe, although most of its territory is in Asia)?

5. Europe and Africa (Turkish Strait, Mediterranean Sea, Strait of Gibraltar)?

6. Yamei (Bering Strait)?

7. North and South America (Panama Canal)?

8. Latin America (southern United States)?

9. Other continents are separated by oceans (for example, Europe and America). Let me add that Greenland belongs to North America, and the land boundary between Asia and Oceania is New Guinea.
