How is mass wasting different from other forms of erosion?

a. it happens suddenly

b. it takes millions of years.

c. it involves chemical reactions.

d. it involves physical forces.

A

Explanation:

Examples of mass wasting are slides, falls, creeps, and flows.  Mass wasting processes are easily observable because they happen fast and suddenly and the changes are vividly evident in very short bit of time.   However, other methods of erosion such as mechanical and physical weathering occur very slowly and it would take many years for the changes associated wth their proceses to be vivid to the naked eye.
