Question

Mass wasting is associated with which speed of movement?

A) imperceptibly slow
B) a few centimeters per day
C) 100 kilometers per hour
D) a few meters per year
E) a wide variety of speeds

Answer 1

Mass wasting is associated with a wide variety of speeds, from very slow movements of a few meters per year to rapid movements that can exceed 100 kilometers per hour.

Step-by-step explanation:

Mass wasting is associated with a wide variety of speeds. It can occur imperceptibly slowly, such as with soil creep, or extremely rapidly, like in the case of a rockfall or landslide. The movement of material in mass-wasting events can range from just a few centimeters per day to speeds exceeding 100 kilometers per hour. For example, soil creep might involve movements of only a few meters per year, whereas a debris flow could travel at speeds comparable to a rushing river. Therefore, the correct answer to your question is E) a wide variety of speeds.
