Question 1

Correct Answer:

Verified

Here is a sample response:
I am in an area that was the top of a rotational slump. The material to my right was the head of the slump area, which rotated inward, changing the angle of the trees to point toward the slope.
A successful answer should
- identify the cause using the term "rotational slump" and
- correctly explain the cause of the angle of the trees.
