Transport by wind How gravity affects slopes - Stress: applied force o Depends on rock type, climate, amount of water - Strain: response to stress - Normal stress: an applied force acting at a right angle to the slope - Shear stress: an applied force acting parallel to the slope - Shear strength: the ability to resist stress o Failure: when slope collapses (e.g. slope sliding J moving rocks down slope) - Slope angle J the steeper the slope, the more likely to fail; depends on the sediment of rock Gravity driven processes (mass wasting) - Flow: turns from a solid sediment to a liquid o E.g. thawing of ice in soil after winter - Fall o E.g. Niagara falls - Slide o Translational slide Strata: layers in the rock parallel with the slope Because the shear strength is low, they will slide Happens when slopes are steep (e.g. rocky mountains) o Rotational slide(slump)
