Geography 2051 Exam 2 - Namikas (LSU)\\ LSU
GEOG 2051 Exam 2 Review – Namikas Notes,
Tips & Practice Questions
Slope
a curve or incline surface that represents the boundary of a land created from weathered material
What's important in knowing how to deal with slopes?
Stability
How are slopes considered systems?
What are the inputs? Outputs?
Inputs: materials that have weathered out of the surface and tumbled down & becomes part of the
slope
Outputs: materials that are carried out into the water
Angle of repose
the steepest angle that a slope can maintain without materials falling further (equilibrium)
What forces affect slope stability? (these cause angle of repose)
-driving forces (gravity & water)
-resisting forces (friction & cohesion)
What are the slope elements?
-waxing slope
-free face/fall face
-waning slope
-debris slope
Waxing Slope
portion of top of slope where angle of the slope is increasing (steepness increases); convex surface
Free Face/ Fall Face
steepest portion of slope
Waning Slope
portion of slope that angle is decreasing (steepness decreases); concave surface)
Debris Slope
zone of material accumulation
