What is Erosion?

What are sediments?

What is Conservation Tillage?
Caring for our world soils in what they are made of, what grows in them and how we use them. It is the responsible planning and management of the soil.
What is Soil Stewardship?
the process of breaking down rock through chemical reactions (ex. oxidation)
What is Chemical Weathering?
This rock is formed when wind and water can break rock into pieces, make a layer. The layer can be buried under other layers of sediments. After a long time the sediments can be cemented together.

What are natural causes of Erosion?
