The biosphere is the space on or near Earth's surface that contains and supports living organisms. It is subdivided into the lithosphere, atmosphere, and hydrosphere. The lithosphere is Earth's surrounding layer, composed of solids such as soil and rock; it is about 80 to 100 kilometers (50 to 60 miles) thick. The atmosphere is the surrounding thin layer of gas. The hydrosphere refers to liquid environments such as lakes and oceans that lie between the lithosphere and atmosphere. The biosphere's creation and continuous existence results from chemical, biological, and physical processes.

Since life exists in the air, on and in the earth, and on and in water, the biosphere overlaps, connects, and influences all of the other spheres - and they all affect the biosphere. Considering the sheer number of organisms on earth, however, the biosphere is actually fairly small in size.
