Mass Wasting/Geological Work

Mass wasting - Things move down hill because of gravity.

Weathering disintegration and decomposition at or near the Earth's surface, decomposition is the most complicated of the two. Weathering must occur before geological work can begin.

    1. chemical weathering decomposition, change a substance into something else, for instance, the result of exposure of rock to rain, wind, etc. might change rock to rust (oxidation) (Fe2O3) and clay minerals. The reason cars and houses are painted (for protection from elements).
    2. physical/mechanical weathering - disentegration, breaking objects into smaller objects/pieces.

Water effect and types of mass wasting

    1. Water is important in mass wasting. Some of its rolls are:

    2. Types of Mass Wasting are:
