Continental mountain ranges rise because the crust becomes where tectonic plates collide.

Thicker

Explanation:

The continental mountain ranges are the large scale features on earth that are formed due to the sharing of a convergent type of plate boundary between two continental plates. They form a sandwich pattern, increasing its thickness, and due to the compressional stress, exerted on it from both sides, it becomes folded and rises, forming high elevated mountains and mountain systems.

The thickness of these mountains ranges from about 40 to 80 km. For example, the great Himalayas.

Thus, the continental mountain ranges rise due to its increased thickness.
