Recharge

Back

Process by which water from precipitation and runoff is added to underground reservoirs of water

Front

Capillary action

Back

The movement of water within the spaces of a porous material due to the forces of adhesion, cohesion, and surface tension

Front

Cohesion

Back

Measure of how well molecules stick to each other, particularly water molecules

Front

Adhesion

Back

Tendency of dissimilar particles or surfaces to cling to one another
