Question

B. Infer what process is most likely causing the Pacific Plate to expand.

Answer 1

The Pacific Plate is most likely expanding due to a divergent plate boundary, which occurs when tectonic plates move away from each other and lead to the production of magma and volcanic activity.

Step-by-step explanation:

The process most likely causing the Pacific Plate to expand is divergent plate boundary. Divergent plate boundaries occur when tectonic plates move away from each other, causing the underlying mantle to experience reduced pressure. This reduction in pressure can lead to the production of magma, which can then lead to volcanic activity.

Answer 2

Divergent margins

Explanation:

The process most likely causing the Pacific Plate to expand is divergent margins. Along a divergent margin, the lithosphere splits and begins to move apart. In a convergent margin, plates are pulling together relative to each other. At a divergent margin, the plates are pulled apart. This leads to the formation of new crusts and it is usually described as a constructive margin. The mantle below is the driving force of the movement of the divergent plates.
