Mountain ranges often appear on the edges of continents. What theory does this support?

Question

Mountains were formed when Earth’s crust cooled and Earth shrank.
Mountain ranges were formed when continents collided.
Mountain ranges did not exist millions of years ago.
Mountain ranges were formed only by glaciers.

Answer 1

The theory that is supported by the observation that mountain ranges often appear on the edges of continents is that mountain ranges were formed when continents collided. This aligns with the theory of plate tectonics, which explains that the movement and interaction of tectonic plates can lead to the formation of mountain ranges through processes such as subduction, continental collision, and other geological activities.
