14. which of the following is an example of an epeirogenic process? o o a. a rift valley forms at a divergent boundary where two plates are stretched apart. b. a large plateau forms in the interior of a continental plate when a large section of the plate rises evenly due to an even expansion of the underlying mantle o c. mountains form along a convergent plate boundary when two plates collide, causing rock to bunch and buckle upward o d. mountains form along a convergent plate boundary when an oceanic plate slips beneath a continental plate, resulting in an upward force on the continental plate

Option (A) and (D)

Explanation: Epeirogenic process refers to the uplifting and sinking of the continental crust. It is the vertical movement of the crust due to certain mechanisms. Divergent movement of the plates leads to the thinning of the crust and in the convergent plate boundary between a continent and oceanic plate, creates an accretionary wedge that increases the vertical height of the crust. It is not related to the continental collision and plateaus are the stable part of the continent where there is not much change in the thickness of the crust.

Thus the correct answers are (A) and (D)

i think it's letter a.
