Answer:
Rocks in the ocean crust and rocks of the continent are similar to each other
Answer:
Option (D)
Explanation:
Continental crust are the thick plates that are about 35-40 km in thickness on an average. They are rich in silicate rocks, and are very old forming land mass on earth.
Whereas, oceanic crust are thin crust that are about 5-7 km in thickness, and are not old like the continental crust and the rocks are mostly basaltic.
Both the continental as well as oceanic crust moves from one place to another due to the plate tectonic movement.
The rocks in the oceanic and continental crust differs from one another. The rocks in the continental crust are made up of silica-rich rocks such as granite, rhyolite. Whereas, the oceanic crust are dominantly comprised of silica-deficit rocks like gabbro and basalt.
Thus, the correct ans is option (D).
