Document Summary

The top layer of soil, characterized by the downward movement of water; also called zone of leaching. A soil layer characterized by the accumulation of material leached downward from the a horizon above; also called zone of accumulation. chemical weathering. The decomposition of rock resulting from exposure to water and atmospheric gases. A soil layer composed of incompletely weathered parent material. clay mineral. A hydrous aluminum-silicate that occurs as a platy grain of microscopic size with a sheet silicate structure. differential weathering. Varying rates of weathering resulting from some rocks in an area being more resistant to weathering than others. erosion. The physical removal of rock by an agent such as running water, glacial ice, or wind. exfoliation. The stripping of concentric rock slabs from the outer surface of a rock mass. exfoliation dome. A large, rounded landform developed in a massive rock, such as granite, by the process of exfoliation. frost action.
