Answer 1

The true statement is as follow:

C. The direction of movement of the Pacific Plate changed about 47 million years ago, which created a bend in the Hawaiian-Emperor hot-spot track.

• The option B is also incorrect as the plates move in response to three mechanism but this option says that there are only two mechanism of movement of plate.
• The option C is correct as the direction of movement of the Pacific Plate changed about 47 million years ago due to which a bend was formed in the Hawaiian-Emperor hot-spot track.
• The option D is also incorrect as the Southwestern California and Baja Peninsula are not moving toward the southwest along the section of the Pacific Plate-North American Plate boundary called the San Andreas fault.
