Aquifer �Body of rock or sediment where large amounts of water flow or is

Aquifer �Body of rock or sediment where large amounts of water flow or is stored

Porosity �% of the rock or sediment with open space �Sorting affects porosity

Porosity �% of the rock or sediment with open space �Sorting affects porosity

Permeability �Ability of a rock or sediment to let fluids pass through �Impermeable –

Permeability �Ability of a rock or sediment to let fluids pass through �Impermeable – water cannot flow Clay

Aquifers �Gravity pulls water down until it reaches an impermeable layer

Zones of Aquifers �Saturation – pore space is completely filled with water �Water table

Zones of Aquifers �Saturation – pore space is completely filled with water �Water table – upper layer of zone

�Aeration – Between surface and water table � 3 layers � 1. Soil moisture
