Question

which statement best describes the geologic process that is most likely responsible for the formation of mountains? they are along a plate boundary in which plates are currently converging, causing uplift and steep slopes. they are along a transform plate boundary that is no longer active, so erosion is creating deep valleys. they are along a transform plate boundary in which plates are currently moving side by side, causing earthquakes and faults. they are along a plate boundary in which plates diverged in the distance past, allowing new rock to build up.

Explanation:

To determine the correct statement about mountain formation, we analyze plate tectonics:

• Convergent plate boundaries (where plates move toward each other) cause uplift, folding, and faulting, leading to mountain formation (e.g., Himalayas from Indian - Eurasian plate collision).
• Transform plate boundaries involve plates sliding past each other, causing earthquakes and faults, not mountain building (eliminates purple and orange options).
• Divergent plate boundaries (plates moving apart) form rift valleys or mid - ocean ridges, not mountains (eliminates teal option).

The yellow option describes plates converging at a boundary, causing uplift (a key process in mountain formation).

Answer:

A. They are along a plate boundary in which plates are currently converging, causing uplift and steep slopes.
