question 18 of 25
the map shows oceanic tectonic plates in the southeastern pacific ocean.
what is likely happening at the boundary between the nazca plate and the pacific plate?
a. rising of magma from the mantle beneath
b. folding of the crust on both plates
c. subduction of oceanic crust beneath continental crust
d. a collision of the two plates

Explanation:

The boundary between the Nazca plate and the Pacific plate is a divergent boundary. At such boundaries, magma rises from the mantle to create new ocean - floor crust. Folding occurs at convergent boundaries where plates collide. Subduction of oceanic crust beneath continental crust is also a feature of convergent boundaries. A collision is characteristic of convergent boundaries. Divergent boundaries are associated with rising magma.

Answer:

A. Rising of magma from the mantle beneath
