cause
Studies have proved that some large and small nebulae were separated from the solar nebula about 5 billion years ago. They revolve around the sun while rotating. In the process of movement, they collided with each other, and some lumps combined with each other, from small to large, and gradually became the original earth.
During the collision of nebula clusters, they shrink sharply under the action of gravity, and the radioactive elements in them degenerate, which makes the primitive earth heat up continuously. When the internal temperature reaches high enough, underground substances, including iron and nickel, begin to melt.
Under the action of gravity, the weight sinks and tends to concentrate in the center of the earth, forming the core; Lighter ones float to form the crust and mantle. At high temperature, the water inside evaporates, rushes out with the gas and rises into the air. But because of gravity, they will not run away, but will only turn around the earth and become a circle of air and water.
