Detailed explanation-2: -The crust is composed of two basic rock types granite and basalt. The continental crust is composed mostly of granite. The oceanic crust consists of a volcanic lava rock called basalt. Basaltic rocks of the ocean plates are much denser and heavier than the granitic rock of the continental plates.

Detailed explanation-3: -There are two types of plates, oceanic and continental. An example of an oceanic plate is the Pacific Plate, which extends from the East Pacific Rise to the deep-sea trenches bordering the western part of the Pacific basin. A continental plate is exemplified by…

Detailed explanation-4: -The crust of the Earth is called as lithosphere. This layer is composed of the mantle and the crust. Most part of the Earth’s crust is covered by the oceans.
