LITHOSPHERE:
_ It is the outer mantle of the solid earth. It contains minerals occurring in the earth’s crust and the soil.
_ The coolest and most rigid part of the Earth.
_ It extends to a depth of about 60 miles (100 km).
_ Three main layers: crust, mantle and core  Crust is the outer most layer
 

 

HYDROSPHERE:
_ Comprises all water resources such as ocean, seas, lakes, rivers, reservoirs, icecaps, glaciers, and ground water.
_ 71% of Earth is covered with water
_ salt water (97%)
 

 

BIOSPHERE: 

 _ It constitutes the realm of living organisms and their interactions with the environment (atmosphere, hydrosphere, and lithosphere)
