GEOG 2051 : Exam 2 Review
Document Summary
Key factors control what kinds of weathering dominate in an area: characteristics of the parent rock, rock hardness, solubility, degree of jointing, cracks in the rock, climate, precipitation, temperature. Influences climate on a localized basis: microclimate. It continues to swell and expand, which causes the cracks to break apart same amount pushing out, so we don"t notice. When we change altitudes, the pressure no longer balance out. Chemical processes: breakdown of materials on a molecular scale, dominates in wetter, warmer climates: solution. Karst landforms: carbonation, dissolving of carbon dioxide in water. Slope: a curve or incline that represents the boundary of a landform, steepness, how quickly elevation increases, tangent = rise/run, slope continues to build to get steeper & steeper in the transport. System: inputs (weathering), outputs (transport), equilibrium, angle of repose. & passes through on the slope: waning slope, decrease, steepness getting smaller. Slope development: rock strength, the stronger the rock, the steeper the slope ends, climate.
