Download 4 spheres and water cycle cornell

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.
Water Cycle

The continuous
movement of
water between
the Earth’s 4
spheres.
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
