Which features are parts of a mountain system?

a. plains plateaus

b. mountain belts

c. individual peaks

d. mountain rang

Answer: b. mountain belts

Explanation:

A mountain system or mountain belt is a combination of the mountain ranges. These mountain ranges share similarities in the alignment, form and their structure. These similarities appear due to the mountain genesis process called as the orogeny. The mountain ranges are generated by the geological processes and plate tectonics.

Option (B)

Explanation:

A mountain belt is usually defined as a series of mountains, which is collectively known as the mountain system. They are characterized by the presence of similar form, structure and are arranged in a preferred orientation. The mountain belts are formed by the orogenic process, where the earth's crust due to the compressive forces bends and rises upward, forming the large mountain and mountain ranges.

The plate tectonic motion is the main factor that is responsible for the formation of mountain belts.

Thus, the correct answer is option (B).
