What is erosion?

(a)  

Is the separation and removal of weathered and unweathered rocks and soil from its substrate due to gravity or transporting agents like water, or wind.

(a)  

Erosion

It detaches soil particles and transports them by the wind. Commonly occurs in flat, bare areas, or dry, sandy, loose soils.

Erosion

Is the most common erosion agent. Millions of tons of sediments is picked-up and transported every day along rivers, coast, and deep oceans around the world.

(a)  

Free-fall movement, bouncing, and rolling of materials on a slope.

(a)  

Is a forward rotation out of the slope of the soil or rock mass

(a)  

Is the downslope movement of coherent materials along a well-defined surface of rupture called sliding surface.

(a)  

Is the lateral extension and fracturing of a coherent mass due to the plastic flow of its underlying material

(a)  

This happens when the materials are saturated and move downslope as a viscous fluid

(a)  

Is the process in which sediments settle out of the transporting medium
