Question

Mountains that have developed because of compressional stress—colliding plates that force rock layers upward—are called _____.

Answer 1

folded mountains

Step-by-step explanation:

A folded mountain is formed when two plates moving together under compression stress.Due to these compression stress thrust line or pressure is created which causes folding of layer within the upper part of earth's crust thereby forming large fold-like structures on the earth's crust.

Most of the existing mountainous ranges are examples of fold mountains

Hence, Mountains that have developed because of compressional stress—colliding plates that force rock layers upward—are called __Folded Mountain

Answer 2

The choices can be found elsewhere and as follows:

a)folded mountains
b)fault-block mountains
c)canyons
d)plateaus

I think the correct answer is option B. Mountains that have developed because of compressional stress—colliding plates that force rock layers upward—are called fault-block mountains.
