地球是怎样形成的我国古代有这样的话:“混沌初开,乾坤始奠,轻清者上升为天,重浊者下沉为地。”这样就形成了一个被大气层包围着的原始地球。后来液体部分逐渐分成地壳、地幔和地核。地壳表面有大量水覆盖和矿物岩石构成的固体陆地,并出现了生物。在各种地质作用下随地表面形成了山地、平原、高原等丰富的地貌。生物着陆后进化发展出一代植物、动物和人类。

How Earth was formed In ancient China, there was a saying like this: “When chaos begins, heaven and earth are laid, light people rise to heaven, heavy turbid people sink to earth.” This created a primitive Earth surrounded by the atmosphere . Later the liquid part gradually divided into the crust, the mantle and the core. There is a large amount of solid land covered by water and mineral rock on the surface of the earth’s crust, and the emergence of living things. In a variety of geological effects along the surface of the formation of mountains, plains, plateaus and other rich landscape. After the biological landing evolved a generation of plants, animals and humans.
