Marine knowledge for children, what to know about the ocean

Children's marine knowledge, the earth is divided into land and ocean plates, most people have a clear understanding of the land, not so clearly understand the ocean, because the ocean is much larger than the land, the world is unknown and there are many, many more, adults should give children science popularization children's ocean knowledge, I will take you to see it.

The ocean is the general term for the most extensive body of water on the earth, the central part of the ocean is called the ocean, and the marginal part is called the sea, which communicates with each other to form a unified water body.

The earth's surface is divided by major landmasses into a vast body of water called the ocean, which has a total area of about 100 million square kilometers, accounting for about 71% of the earth's surface area, and an average water depth of about 3,795 meters. The oceans contain more than 1.35 billion cubic kilometres of water, about 97 per cent of the planet's total water, and only 2 per cent of it is available for human consumption.

The four main oceans of the earth are the Pacific Ocean, the Atlantic Ocean, the Indian Ocean, and the Arctic Ocean, most of which are bounded by land and submarine topography. So far, only 5% of the seabed has been explored, and 95% of the seabed is unknown.

The central part of the ocean is called the ocean, and the edge part is called the sea, and they communicate with each other to form a unified body of water. The oceans cover nearly three-quarters of the Earth's surface and account for 97% of the Earth's total water resources, and by volume, they account for 99% of the space that life can develop on Earth. The temperature, chemical composition, currents, and organisms of the oceans affect the ecosystems that humans inhabit around the globe.

For example, rainwater, drinking water, climate, food, etc. are all provided and regulated by the ocean.

Ocean: The ocean is the general term for the most extensive body of water on the earth, and the earth's surface is divided by major landmasses into vast bodies of water that communicate with each other called the ocean. The total area of the Earth's oceans is about 100 million square kilometers, accounting for about 71% of the Earth's surface area, and the average water depth is about 3,795 meters.

The oceans contain more than 1.35 billion cubic kilometres of water, about 97 per cent of the planet's total water, and only 2 per cent of it is available for human consumption. The four main oceans of the earth are the Pacific Ocean and the Atlantic Ocean.

Indian Ocean, Arctic Ocean.

Most of them are bounded by terrestrial and submarine topographic lines. Because the Earth's oceans are much larger than the land area, some people refer to the Earth as a "big water ball". The Pacific, Atlantic and Indian oceans account for % and 20% of the Earth's oceans, respectively.

The important marginal seas are mostly found in the northern hemisphere, and they are partly surrounded by continents or islands. The largest are the Arctic Ocean and its offshores, the Mediterranean Sea in Europe, the Caribbean Sea.

and the waters near the Red Sea, the Bering Sea, the Sea of Okhotsk, and the Yellow Sea.

East China Sea and Sea of Japan.

The earth is called "water."

"Sphere", because most of the earth is covered by seawater, 71 percent of the earth is ocean, and only 2 percent is back to land.

Axi. It can be seen that the ocean area on the earth is huge, and this ocean is divided into five oceans, namely the Pacific Ocean, the Atlantic Ocean, the Indian Ocean, the Arctic Ocean, and the Southern Ocean. The Pacific Ocean covers nearly half of the world's ocean area, and the other four oceans: the Atlantic, Indian Ocean, Arctic Ocean, and South Arctic Ocean account for half.
