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?
O
A. Rising of magma from the mantle beneath
O
B. Subduction of oceanie crust beneath continental crust
O
C
Folding of the crust on both plates
O
D. A collision of the two plates
The oceanic tectonic plates between the Nazca plate and the Pacific plate are showing subduction of oceanic crust beneath continental crust. Thus, option B, is correct.
What are oceanic tectonic plates?
In the tectonic plates the oceanic crust are the top most layer in the oceanic portion. They lie primarily under the ocean. They are made up of denser rocks and composed of Basalt.
In the given map the two oceanic plates are subducting within each other.
