Question

The oceanic Nazca plate is being subducted beneath the continental South American plate. Which type of plate boundary is this?

Answer 1

Answer:

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.

Answer 2

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.
