Mendocino Coast Erosion
Erosion is the removal of solids (sediment, soil, rock and other particles) in the natural environment. It usually occurs due to transport by wind, water, or ice; by down-slope creep of soil and other material under the force of gravity; or by living organisms, such as burrowing animals, in the case of bioerosion. This figure shows the effects of erosion on the rock formation along the coast of the Mendocino Coast in California.
