State the difference between erosion and mass movement and list four agents responsible for modifying landforms

(a) State the difference between erosion and mass movement.

(b) List four agents responsible for modifying landforms.

(c) Outline three factors that influence mass movement.

Explanation

(a) Erosion is the dislodging of sediments that initiates their movement. Particles may then be moved away by sediment transport agents such as wind, water, glaciers, etc. Mass movement refers to earth materials moving downslope under the influence of gravity, as in rockslides, mudflows, slumps, etc.

(b)

1. Erosion
2. Deposition
3. Weathering
4. Biological influence

(c)

1. Composition of Slope Material
2. Weight and Friction of Slope
3. Regional Climate Conditions
