Explain three physical factors that enhance movement of materials along a slope due to gravity.
Answer:
-Heavy and large materials moves faster on a slope as they are more likely to be
overcome by gravity.
-Angle of slope-the steeper the slope, the faster the rate of movement. Where rocks
are dipping steeply, movement is faster.
-Climate factor/amount of water-the saturated the rock or soil or material is,
the more likely it is to move as water adds weight and lubricates. Alternate freezing and thawing encourages movement.
-Vegetation cover-bare surfaces are more likely to experience mass wasting because there is no vegetation to bind the material together.
-Earths movement- earthquakes or volcanic eruptions cause vibration
which may trigger widespread movement of weathered rock materials
