Valleys and mountain ranges form through the process of tectonic activity. When tectonic plates collide or separate, they can create a variety of landforms. Mountains are formed when two plates collide and force the earth's crust to buckle and fold, resulting in upward movement and the formation of a mountain range. Valleys, on the other hand, can be formed through different processes, including erosion by rivers, glaciers, or tectonic activity that causes the land to sink and create a depression. Overall, the formation of valleys and mountain ranges is a complex process influenced by geological forces and erosion.

Tectonic activity creates valleys and mountain ranges. When plates collide, mountains form as the earth's crust buckles and folds. Valleys can form from erosion by rivers, glaciers, or sinking caused by tectonic activity. The formation of these landforms is influenced by geological forces and erosion.
