Definition of groundwater

Groundwater- Water held underground in the soil or in pores and crevices in rock.

What processes make water groundwater? Infiltration helps in the process by which water on the ground surface enters the soil.

Porosity vs. Permeability

Porosity - A measure of how much of a rock is open space.

Permeability- The ability of a substance to allow another substance to pass through it.

How does Porosity & Permeability affect the presence of groundwater? Porosity and permeability are two factors that help determine the materials to make a aquifer.
