Question

identifying evidence from land features mountain ranges often appear on the edges of continents. what theory does this support? 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.

Explanation:

This aligns with plate tectonics theory: when continental tectonic plates collide at continental edges, the crust crumples and uplifts to form mountain ranges, which matches the observation of mountain ranges at continent edges. The other options are incorrect: the cooling/shrinking Earth theory is disproven, mountains did exist millions of years ago, and glaciers only shape (not form) some mountains.

Answer:

Mountain ranges were formed when continents collided.
