Soil Formation Over many years, weathering and erosion will cause the formation of soil. Soil is the loose, weathered material on the Earth’s surface in which plants can grow. Soil forms as rock is broken down by weathering and mixes with other materials on the surface. Soil Composition Soi...

Comes from decaying plants and animals. The same factors that control weathering control soil formation with the exception, that soils also requires the input of organic material as some form of Carbon. Soil Formation Soil Erosion In most climates it takes between 80 and 400 ...
4) As these rills pass over fine soil or silt, they begin to dig shallow channels, called gullies. This is the first stage of erosion. A gully only has water in it when it rains. 5) A stream is formed when gullies join together. It is a channel along which water is continually fl...
