Hydrosphere

Answer 2

The realm of land is called lithosphere, the realm of water is called hydrosphere and the realm of air is called atmosphere.

The narrow zone where land, water and air meet is called biosphere. It is the fourth realm of the earth and it supports life.

One of the reasons for supporting life is that the earth has plenty of water on its surface. The first life on the earth is originated in water.

The outer solid layer of the earth is called crust or lithosphere. The word lithosphere comes from a Greek word Lithos which means rock. So, the crust or lithosphere is made up of rocks.
