Here's why:
* Convergent boundaries occur when two tectonic plates move towards each other.
* The immense pressure from the collision forces the edges of the plates to buckle, fold, and uplift, creating mountain ranges.
There are three main types of convergent boundaries:
* Oceanic-Continental Convergence: An oceanic plate subducts (dives) beneath a continental plate. This process often leads to volcanic mountain chains along the continental edge.
* Oceanic-Oceanic Convergence: Two oceanic plates collide. The denser plate subducts, often resulting in volcanic island arcs.
* Continental-Continental Convergence: Two continental plates collide. Neither plate can subduct, so the collision leads to the formation of massive mountain ranges. The Himalayas are a prime example of this type of convergence.
