The large boulders break and fall from the cliffs, and by the weath- ing of the rains, frosts and other agencies, they are worn away.

Soils formed in this way by the deposit of the sediment from running water are called sedimentary soils. In some cases the rocks break up and are not. Fig. 33. Soil formation. Rain, frost and plants
