Ground level: Plants grow and animals live
here. A thick cover of plants can keep the soil
cool and keep it from drying out. Decomposers
recycle dead plants and animals into humus.
This is the soaking
into the ground of
water on the
surface.
 The fluid moves
through pores or
spaces between
grains of soil.

INFILTRATION OF WATER INTO SOILS.
PORE SPACE AND SATURATION
PORE SPACE. (POROSITY) THE PERCENT OF
SPACE BETWEEN SEDIMENTS.
PERMEABILITY
The ability of body of rock, soil or sediment to
allow fluid to pass through it.
 Optimum permeability is when there are large
and rounded sediments.
 The smaller or finer the sediments the slower
the movement of fluids.
 Clays act as stops for the movement of fluids
because the do not have much pore space.

PERMEABILITY THE SPEED AT WHICH FLUIDS
MOVE.
CAPILLARITY- THE ABILITY OF FLUID TO
MOVE UPWARD DUE TO ADHESION
