Question

Based on the properties of density and the earth's crust, what is the BEST prediction of the movement of oceanic and crustal plates?

OA. Oceanic plates contain basaltic rocks and will sink under crustal plates.
Oceanic plates contain granitic rocks and will rise over crustal plates.
Crustal and oceanic plates have the same density, so no movement will occur.
D. Oceanic plates contain light basaltic rocks that will float over crustal plates.
B.
C.

Answer 1

Oceanic plates containing basaltic rocks will sink under crustal plates.

Step-by-step explanation:

The best prediction of the movement of oceanic and crustal plates is that oceanic plates contain basaltic rocks and will sink under crustal plates. This is because basaltic rocks are denser than granitic rocks, which make up the crustal plates. Due to their higher density, the oceanic plates will subduct underneath the less dense crustal plates.
