Question

multiple-choice question
what caused the san andreas fault to form?
poor life choices
volcanic activity at the ends of the fault
two tectonic plates sliding past each other
groundwater infiltrating into the mantle

Explanation:

The San Andreas fault is a transform fault formed by the Pacific Plate and the North American Plate sliding past each other horizontally. "Poor life choices" is irrelevant. Volcanic activity at fault ends doesn't cause the fault's formation. Seawater infiltrating the mantle isn't related to this fault's formation. So the correct reason is two tectonic plates sliding past each other.

Answer:

C. Two tectonic plates sliding past each other (assuming the options are labeled A, B, C, D with A: Poor life choices, B: Volcanic activity at the ends of the fault, C: Two tectonic plates sliding past each other, D: Seawater infiltrating into the mantle)
