Continental-continental plate collisions produce

large mountain ranges, such as the Himalayas. These collisions occur when two continental plates converge and are unable to be subducted due to their similar densities. Instead, the crust buckles and folds, creating massive mountain ranges and causing earthquakes and volcanic activity. The collision of the Indian Plate and the Eurasian Plate is a well-known example of a continental-continental plate collision, which resulted in the formation of the Himalayas.
