Soil Orders
Alfisol- moderately leached
Andisol- formed in volcanic ash
Entisol- little or no morphological development
Histosol- organic soils
Inceptisol- weakly developed subsurface horizons
Mollisol- grassland soils with high base status
Oxisol- highly weathered soils
Ultisol-strongly leached soils
Vertisol-clay rich soils
Gelisol
Spodosol
AridisolSlide8
Soil Erosion
Natural occurring process
Affects all landforms
Wearing away of topsoil
Natural forces act on the soil
More exposed heavy tilled soil is = more likely it is to erode during rain or windstorms.
