Shiloh Kaufman · Answer 1

Option (A), (C) and (D)

Explanation:

Continental crust refers to the thick landmasses that are found on the earth and are very old. They are usually about 10-40 km thick and in the high mountains like himalaya, their thickness ranges upto 80 km.

The continental crust are usually made up of silicates, oxides, and carbonate minerals. They are thicker and also their density is low in comparison to the oceanic crust. This is the reason why continental crust are the over-riding plates when collides with an oceanic crust. Granite is formed on the continental crust when hot intruding magma gets crystallizes.

The crust does not show any plastic behaviour but it is being shown by the asthenosphere due to the presence of viscous fluid materials.

Thus, the correct answers are option (A), (C) and (D).
