Question

Which geologic process described causes the formation of a mountain? Select all that apply.

a. New rock is created when magma cools and hardens at Earth’s surface.
b. Rock layers are compressed and forced upward.
c. Bedrock breaks into faults, forcing some of the blocks up and others down.
d. A denser tectonic plate is pushed beneath a lighter plate, deep into the mantle.

Answer 1

The geologic processes that cause the formation of a mountain are rock layer compression, faulting, and subduction. Therefore, the correct option is B,C , D.

Step-by-step explanation:

The geologic processes that cause the formation of a mountain are:

• Rock layers are compressed and forced upward: When two continental masses are moving on a collision course, they push against each other under great pressure, causing the rocks to buckle and fold. This uplifts the rock layers and forms mountains.
• Bedrock breaks into faults, forcing some of the blocks up and others down: This process, known as faulting, occurs when the bedrock breaks along fault lines. The blocks on one side of the fault may be pushed up, while those on the other side may be pushed down, resulting in the formation of mountains.
• A denser tectonic plate is pushed beneath a lighter plate, deep into the mantle: This process, known as subduction, occurs when one tectonic plate, which is denser, is forced beneath another plate that is lighter. This movement can lead to the formation of mountain ranges.
