How big is the land area of the earth and what is the land area of the earth?

The total surface area of the earth is 510 million square kilometers.

The earth's land area is 149,000,000 square kilometers, accounting for 361,000,000 square kilometers of the earth's surface area. If there is an undersea volcanic eruption, then some islands may be added, and the land area will become larger. If the glaciers melt and the sea level rises, the land area becomes smaller.

Even human land reclamation will make the land area larger.

The Earth's land area is 100 million square kilometers. The Earth's surface area is 100 million square kilometers, of which 100 million square kilometers are land, accounting for % of the global surface area. The remaining 71% is marine.

There are six continents in the world, including the Eurasian continent, the African continent, the North American continent, the South American continent, the Australian continent and the Antarctic continent, with a total area of 100 million square kilometers, accounting for about 93% of the total land area; The small piece of land surrounded by sea is called an island, with a total area of 9.8 million square kilometers, or about 7% of the total land area.

Division of the Earth's land area:

The largest continent is Eurasia, bordered by the Pacific, Indian and Arctic Oceans to the east, south and north, respectively, and the Mediterranean Sea and the Black Sea to the northwest of Southwest Asia. The northernmost point of the mainland is Cape Cheliuskin (77°44 N) on the Tamyr Peninsula, and the southernmost point is Cape Piai (1°15 N) on the Malay Peninsula; The northernmost point of the island is in the North-Zemlya archipelago (81°N) and the southernmost point is in the Nusa Tenggara archipelago of Radi Island (10°45 N).

Asia spans the widest latitude of any continent and has almost all climatic and natural zones from the equatorial to the Arctic. The easternmost point of the continent is Cape Dezhniov (169°45 W) on the Chukotka Peninsula and the westernmost point is Cape Baba (26°10 E) on the Asia Minor Peninsula, which spans the widest longitude and has an east-west time difference of 11 hours.

Eurasia is the collective name of the European continent and the Asian continent. This is because the European continent and the Asian continent are connected. From the perspective of plate tectonics, the Eurasian continent is composed of the Eurasian plate, the Indian plate, the Arabian plate, and the North American plate, where East Siberia is located.

The Earth's land area is 100 million square kilometers, % of the global surface area, and the remainder is covered by water, mostly by oceans, bays, and other saltwater bodies, but also by lakes, rivers, and other freshwater, which together make up the hydrosphere.

Earth is the densest planet in the solar system and the largest and most massive of the four rocky planets, which are the homes of human beings living together, and there is only one Earth for human beings.

Formation of the Earth:

The history of the earth is very long. According to radiocarbon dating, the solar system was formed about 6.5 billion years ago, while the native Earth was formed about 6.5 billion years ago.

Theoretically, the formation of the Sun began with the gravitational collapse of a huge cloud of hydrogen molecules 6.5 billion years ago, and most of the collapsed masses were concentrated in the center, forming the Sun; The rest of the space rotates and flattens out to form a protoplanetary disk, which in turn forms planets, moons, asteroids, comets, meteoroids, and other small solar system bodies.

The nebula hypothesis asserts that the microplanets that form the Earth originate from the massaching masses of gas, ice particles, and dust with a diameter of 1 to 10 kilometers that are left over from accretion and collapse. These materials grew over 10 million to 20 million years to form the native Earth. The nascent Earth's surface is an "ocean" of magma.
