Land Sea Notes, Earth s Land Sea

Looking at the Earth from space, the Earth is a blue planet. The Earth's land area accounts for 29% and the ocean area accounts for 71%, so the earth has a nickname called "water balloon".

Only 29% of the land mass is separated by the ocean, and the large chunks of land are called continents. There are six continents in the world, namely Eurasia, Africa, North America, South America, and Australia.

continents and the Antarctic continent.

The continent and its nearby islands are called continents together. The globe is divided into seven continents.

i.e. Asia, Europe, Africa, North America, South America.

Oceania and Antarctica.

The oceans, which cover 71% of the Earth's area, are divided by land into four interconnected oceans.

i.e. the Pacific Ocean, the Atlantic Ocean.

Indian Ocean and Arctic Ocean.

The Pacific Ocean is the largest, at about 180 million square kilometers, covering almost half of the Earth's oceans. The other three oceans account for the other half, with the Arctic Ocean being the smallest, at about 13 million square kilometers.

The world's land and sea are unevenly distributed. Most of the land is located in the Northern Hemisphere, while the North Pole is surrounded by an ocean.

Most of the oceans are located in the Southern Hemisphere, while the South Pole is surrounded by continents.

Isn't that interesting? In the dark, nature seems to be seeking a balance!

On the earth's surface, there are earthy yellow lands and blue oceans, and the vast sea water occupies 71% of the earth's surface area. The land is scattered in the middle of the ocean, dividing the vast surface of the water into four interconnected oceans, which we call the Pacific, Atlantic, Indian and Arctic Oceans. The distribution of oceans on the Earth's surface is uneven, with less in the northern hemisphere and more in the southern hemisphere.

Therefore, the southern hemisphere is called the water hemisphere and the northern hemisphere is called the land hemisphere.

Ocean. The oceans are divided into oceans, seas, and straits. The main part of the ocean is the ocean, which is far from the continent and accounts for 89% of the total area of the ocean, most of which are above 2,000 meters deep.

The sea is the marginal part of the ocean, connected to the land, and is much smaller in area and depth than the ocean. The sea area bordering the continent and separated from the ocean by a peninsula or island is called a marginal sea; The inland sea is called the inland sea, which juts out into the interior of the continent and is connected to the ocean edge sea by only a narrow waterway. The sea located between two continents is called the intercontinental sea, also known as the Mediterranean Sea. A narrow channel of water connecting the ocean with two outlets is called a strait.

Land. The parts of the Earth's surface that are not submerged by sea water are collectively referred to as land. There are six continents in the world, in order of size: Eurasia, Africa, North America, South America, Antarctica and Australia. The average altitude of the land is 875 meters.
