LAB TITLE:

POROSITY AND PERMEABILITY

POROSITY - The amount of open pore space between particles of a material.

PERMEABILITY-The ability of rock and soil to allow water to pass through

IMPERMEABLE- Rock materials that do not not allow water to pass through.

WATER RETENTION- Water retained by the rock

INFILTRATION- Process of water moving down into the ground beneath the rock particles.
