Biosphere is made up of all the living organisms on the planet. These living things are found on the surface, underground, and even those reaching a kilometer above the surface of Earth. Biosphere includes the plants, animals, bacteria, and fungi that thrive on the planet even in the most ex treme environments in the depths and corners of Earth.

 

Geosphere

Geosphere, from the Greek word ground, is composed of all the rocks, minerals, and soil on Earth. This includes not only the mountains, continents, ocean floor, sand in the deserts, and bedrocks but it also includes Earth's interior layers. Earth is further subdivided based on how the materials found on its geosphere react with and behave to different factors and forces in the environment. Lithosphere refers to the solid and rigid outer layer that includes the crust and the uppermost part of the mantle. Below this sphere is the asthenosphere, which consists of the solid but mobile part of the mantle that can flow depending on the heat deep within Earth.
