Answer 1

Answer:

A, Mass movement: mass movement (often called mass wasting) is the downslope movement of a mass of surface materials such as soil, rock, or mud

Answer 2

"Mass Movement" is the direct movement of materials by the effect of gravity.

Option (a);

EXPLANATION:

• "Mass Movement"  typically occurs along the hillsides and mountains.
• It means the "movement of soil, rock, mud or snow" down the slope due to gravity.
• The main reason for this movement is the "angle of the slope" of the hill.
• If it is "steep in angle" the gravity pulls the materials in downside causes mass movement.
• The "angle of the slope" used to determine the fast movement of the materials in the downside direction and it happens either very quickly or very slowly.
• "Mass movement" is also called "mass wasting".
