What are the subsystem of the earth

Hydrosphere, Lithosphere, Atmosphere and Biosphere

Explanation:

Everything present in earth from rocks to small stones and from huge oceans to small water living bodies can be divided into four sub-systems which are also know as earth's spheres. These are land or Lithosphere, water or hydrosphere, air or atmosphere and living things or biosphere.

Hydrosphere is the zone of earth that contains all the gaseous, solid and liquid water present on the surface of earth. It includes the water of oceans as well as huge ice capped mountains' water content.Lithosphere is the zone of earth that contains hard and cold land on earth whether it is present in the form of rocks, sand dunes or hilly scenic areas.Biosphere is simply the living part of the earth that contains all living bodies from pants to insects, fungi and animals that are able to reproduce a fertile generation and fulfill the definition of life.Atmosphere comprises all the gaseous part of the earth that is called air.
