In three to five sentences, explain how the valleys and mountain ranges form

Answer 1

Valleys and mountain ranges form through the processes of tectonic activity and erosion. Tectonic activity occurs when the Earth's lithospheric plates collide, separate, or slide past each other, creating geological features such as mountains and valleys. When two plates collide, they can cause the Earth's crust to buckle and fold, resulting in the formation of mountain ranges. Over time, the action of water, wind, and ice erodes the elevated areas, carving out valleys between the mountains.
