Further research showed that the rocks were chemically and geologically the same and came from the same magma source. This discovery provides evidence of--
coastal erosion
plate tectonics
ocean currents
glacial melting
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They are along a transform plate boundary that is no longer active, so erosion is creating deep valleys.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.
