Question

which of the following is not a primary cause of eroding rock?
a. moving water
b. gusting wind
c. animal habitation
d. gravity

Explanation:

To determine which is not a primary cause of eroding rock, we analyze each option:

• Moving water (A) is a primary agent of erosion, as water can carry sediments and wear down rocks.
• Gusting wind (B) causes wind erosion, transporting particles and eroding rock surfaces.
• Gravity (D) contributes to erosion through processes like mass wasting (e.g., landslides), moving rock and soil.
• Animal habitation (C) generally involves activities like burrowing, which is more related to biological weathering or minor disturbance, not a primary cause of rock erosion compared to the other options.

Answer:

C. animal habitation
