Final answer:
When two plates collide with enough force, folding occurs, breaking the crust.
Step-by-step explanation:
When two tectonic plates collide with enough force, the crust can break due to the intense pressure and stress. This process is known as folding. Folding refers to the bending and warping of rocks and layers of the Earth's crust as a result of compressional forces. The collision of plates can cause the crust to buckle and fold, forming mountain ranges.
