Question

Which of the following is an example of an epeirogenic process?

A. 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.
B. 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.
C. A rift valley forms at a divergent boundary where two plates are stretched apart.
D. Mountains form along a convergent plate boundary when two plates collide, causing rock to bunch and buckle upward.

Answer 1

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. - is an example of an epeirogenic process.

Step-by-step explanation:

Answer 2

A. 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.

Step-by-step explanation:

A large plateau which forms in the interior of a continent, probably a stable part of a continent called a craton as a result of sections rising from the expansion of the underlying mantle typifies an epeirogenic process.

An epeirogenic process is usually associated with the vertical movement of the interior part of the continents. This movement can be as a result of so many tectonic forces which acts within the earth surface. For example, the underlying mantle can expand to force large sections of the earth up. When we have this kind of vertical movement within the earth crust, it is an epeirogenic movement.

The other options in the question are all Orogenic processes which are often referred to as mountain building processes. They are mostly associated with horizontal movement of plates usually at plate margins. For example, the Himalaya Mountain Range is as a result of an Orogenic event.
