The oceanic nazca plate is being subducted beneath the continental south american plate. which type of plate boundary is this?
a. continental-oceanic convergent
b. oceanic-oceanic convergent
c. divergent
d. strike-slip
e. transform
me

Answer;

A. continental-oceanic convergent

Explanation;A convergent boundary is a type of boundary where two plates collide and push against one another.A continental-oceanic convergent is a type of convergent boundary that occurs as a result of subduction. Subduction occurs where a continental plate collide thus resulting to the oceanic plate being pushed underneath the continental plate into the mantle since the oceanic plates are much thinner. The result is that the oceanic plates melts into hot magma which that burns its way up through the continental plate forming a volcano and also causing earth quakes.

A. continental-oceanic convergent

Explanation:

Convergent boundaries are found in places where two plates move towards each other.Continental-oceanic convergent is a type of convergent boundary which is formed if one plate which has an oceanic crust on the top movers toward another plate which has a continental crust on the top.In the given scenario the Nazca plate is topped by the oceanic crust whereas the South American plate is topped by continental crust and as they move towards each other continental-oceanic convergent plate boundary is formed.
