Two continental plates meet and formed folded mountains

When two continental plates meet, they can form folded mountains through a process called continental collision. Continental collision occurs when the two continental plates collide head-on, and the force of their collision causes the rocks on the edges to crumple and fold.

As the two plates continue to collide, compressional forces accumulate, causing the rocks to buckle and bend. This bending and folding of the rocks form a series of parallel ridges and valleys, creating a folded mountain range.

During the folding process, layers of sedimentary rocks that were originally horizontal become tilted or even overturned. The folding can vary in scale, from gentle folds to tight, complex folds depending on the forces involved and the rocks' resistance to deformation.

Over time, erosion takes place and exposes the folded mountain range. The erosion process removes the overlying rocks, leaving behind the uplifted folded structures. Some famous examples of folded mountain ranges include the Himalayas in Asia, the Alps in Europe, and the Appalachians in North America.

Folded mountains are often characterized by high peaks, deep valleys, and steep slopes. Additionally, they are usually found in regions with active tectonic activity, such as convergent plate boundaries, where the collision and compression forces are ongoing.
