Question

Which type of mountain is formed due to the collision of two different kinds of plates?

Answer 1

D) Andean mountains are formed due to the collision of two different kinds of plates.

Answer 2

Answer:

D. Andean

Explanation:

The Andean mountain is formed when two different lithospheric plates converge. The continental plates and the oceanic plates collides to from this kind of mountains.

The oceanic plates is more denser and less thicker than the continental plates . The rock morphology contributes to the heavy density of the oceanic plates as it contain more heavier rocks like the Mafic rocks which are mainly basaltic. As the two plates collides the more denser plates (oceanic plates) subduct due to it limited ability to gain active buoyancy.

The molten magma rises from the subduction zone through the continental crust . The magma becomes more solidified on the continental crust and become more active .Regional metamorphism occurs within this active zone. An uplift may likely occur due to the mobility of the continental crust to form mountain belts and hills like the Andean mountains.
