What is the Hydrosphere explain?

Answer 1

The Earth is a sphere, meaning it is round, like a ball. It is composed of concentric layers. There is an inner and an outer core, which are composed of nickel and iron. These are in the center of the Earth. The next layer above that is made of hot, liquid rock called magma; that can be called the lithosphere meaning rock sphere. Above that is the crust, which we live on. The crust is also made of rock, but it is cooler, solid rock. Most of the crust is covered by oceans, which are made mostly of water. This layer of water can be called the hydrosphere, although it is not a perfect sphere; it does not cover all of the crust. And the next and final layer above the crust and the hydrosphere is the atmosphere, which is made of gas. Above that is outer space.
