GEOG 2051 : Exam 2 Notes
Document Summary
A curved or inclined surface that represents the boundry of a land form. Plays a key role in what they can be used for. Rise (how far we go up) over run. When you multiply the tangent by 100. Inputs are coming from weathering: over time as weathering continues material with pile up, get output from the movement of materials (mass movement, angle of repose. Steepest angle that a given material can maintain and the equilibrium. More friction the harder it is for materials to move: cohesion. Is the action or property of like molecules sticking together, being mutually attractive. Increasing the angle of the slope: freeface (fallface) slope. Materials gets weathered out (input: waning slope. Extremely slow centimeters at a time: moisture. Very wet or very dry: materials. Some water, but not needed: true fall. Friction and energy are lost in this type: flows, slides. Materials move as a cohesive chunk: creep.
