Biosphere Bio = Life Contains ALL living organisms Smallest to largest, on land or in water
Lithosphere Litho = stone A.K.A. Geosphere All layers of the Earth (Crust, Mantle, Core)
Hydrosphere Hydro = water ALL water (below ground, on land, in sky) Can be solid, liquid, or a gas
Atmosphere Atmo = air/vapor All gases found in ground and above the Earth’s surface
Sphere Interactions Spheres are always interacting with each other A change in one sphere can cause an effect in another sphere Ex: A lake (hydrosphere) dries up causing all the aquatic life (biosphere) to die.
The continuous movement of water between the Earth’s 4 spheres. Water Cycle
Convection Circulation of gases or liquids due to thermal energy
Evaporation Occurs when liquid water absorbs thermal energy Liquid changes to gas
Condensation occurs when water vapor loses thermal energy changes from a gas to a liquid
Precipitation Rain, hail, sleet, snow
Runoff Water on the surface Collects in lakes, rivers, oceans
Infiltration Water that is absorbed into the ground Collects in the water table (groundwater)
Transpiration Evaporation that plants perform during photosynthesis
