WEATHERING AND MASS WASTING LECTURE NOTES


VOCABULARY: erosion; agents; base level; weathering; physical or mechanical; frost wedging; exfoliation; plant wedging; chemical; carbonation; oxidation; hydration; hydrolosis; solution; mass wasting; talus; talus cones; block falls; avalanches; rock glaciers; landslides; mudflows; slump; creep; solifluction

erosion--the wearing away of the earth's surface by natural processes
agents--gravity, wind, running water, ground water, glaciers, waves; acts to lower land to base level
weathering--the breakdown of existing surface and near surface material

2 classes of weathering
factors affect rate

erosion--involves an agent

One agent of erosion is gravity.

Agent = Gravity
Process = MASS WASTING

Mass Wasting--downslope movement of solid, solid and liquid material under the influence of gravity

3 variables: Mass Movements

talus
solifluction--slow downslope movement of saturated soil at high latitudes
