Which statement best describes the geologic process that is most likely responsible for the formation of mountains?

• They are along a transform plate boundary that is no longer active, so erosion is creating deep valleys.

• They are along a transform plate boundary in which plates are currently moving side by side, causing earthquakes and faults

• They are along a plate boundary in which plates are currently converging, causing uplift and steep slopes.

• They are along a plate boundary in which plates diverged in the distance past, allowing new rock to build up.
