=== Soil Texture and the Soils Triangle ===
[[File:Site evaluation 03.jpg|right|200px]]
Soils are composed of individual particles of sand, silt and clay, as well as organic matter in various stages of decomposition. The soils triangle shown to the left was developed to classify a soil sample based on its texture, which is based on the relative amounts of sand, silt and clay. Once a soil texture has been identified, you can readily obtain information about the nature of the soils.

In addition to the soil texture, how the soils were laid down over geologic time influences how water moves through the soils.
