Where does your faucet water come from?

Long Island consists of gravels, sand, silt and clays

Ground Water

• Water below the Earth’s surface

Pore - space between the sediments

Porosity - total amount of pore space

Unsaturated - pores filled with air and water (Zone of Aeration)

Saturated – pores filled with water (Zone of Saturation).

• Water Table:

– Boundary between saturated and unsaturated pores in the ground.

FQ:

Water enters the atmosphere by which

two processes? (I want the names).

• Evaporation and Transpiration =

• Evapotranspiration
