Clay is the result of feldspathic rock that has been broken down over many eons, by water, snow, ice, wind, and erosion – weathering. Feldspar , one of the common clay-forming minerals, comprises about 60% of the earth’s crust.
What is the source of clay soil?
Erosion is one source of particles for clay soils and it occurs when water rushes over the surface of rock. However, the largest source of clay particles is from weathering of rocks and soil. During weathering, both physical and chemical changes take place that create the small particles required to form clay soil.
