Pores | different sized spaces |

Permeable | materials that allow water to easily pass through or permeate |
Give examples of permeable | sand and gravel |
impermeable | materials that water cannot pass through easily |
Give examples of impermeable | clay and granite |
True or false: once water reaches an impermeable layer it is trapped | true |
Saturated zone | area of permeable rock or soil that is totally filled, or saturated, with water |
