Question

The map shows oceanic tectonic plates in the southeastern Pacific Ocean.

Answer 1

Answer:

Divergent

Explanation:

Answer 2

Answer:

A: Rising of magma from the mantle beneath

Explanation:

Since the AP map shows arrows going outward of the Nazca and Pacific plate boundary, it is impossible that (D) a collision of the plates is happening, Since the arrows indicate separation.

Subduction is the process in which one tectonic plate (oceanic) is pushed under the other (continental) plate, so it isn't possible that (C) Subduction is happening.

Folding of the crust (B) is usually indicated by mountain ranges, such as with the Indian and Eurasian tectonic plates. This is clearly not the case, so therefore (B) folding of the crust is impossible.

Therefore, it is (A).
