(a)(i) Differentiate between erosion and mass movement.
(ii) Name two features each of river erosion and mass movement.
 
(b) Describe the factors that affect mass movement.

Many candidates attempted this question. Thy were able to rightly define erosion but some could not tell precisely what mass wasting is. Some did not use such linking words as "while" to differentiate correctly the two concepts. Mass movement involves movement of materials down slope due to gravity.
