Plate Tectonics

Question 1 • 2026-27 AL-Earth and Space Science

Many more earthquakes occur along the San Andreas Fault in California than in other parts of the United States. Scientists claim that these earthquakes are caused by activity along a transform plate boundary.Which evidence would best support this claim?

Answer
A
Subduction causes new crust to form.
B
Subduction causes old crust to be destroyed.
C
Plates slip past each other at the boundary.
D
Plates collide with each other at the boundary.

Explanation

A transform plate boundary is where two tectonic plates slide past one another. The San Andreas Fault marks this kind of boundary, and the plates’ movement builds up and releases stress as earthquakes. Therefore, the best supporting evidence is that plates slip past each other at the boundary.
