There are three types of plate collisions. They are classified by the type of crust involved in the collision. Plate collisions fall into these three types: First both plates have an oceanic leading edge. Second one plate has a continental leading edge and the other has an oceanic leading edge, and last both plates have a continental leading edge.
This week I traveled to see the Himalaya Mountains. Collision boundary land forms form great mountain chains on Earth. The Himalaya Mountains are one example of the land forms that are visible on Earth where continental crusts came together. Convergent boundaries are formed when two plates on the earth's surface collide. This may cause one of three things to happen. One, one plate will be forced under the other causing a trench and creating mountain ranges, two, the two plates will crumple together like an accordion and push up forming mountain ranges like the Himalayas, and three the may remain stationary possibly causing earthquakes and increasing the pressure of the lithosphere.
The growth of the Himalayas happened about 220 million years ago when Pangea was breaking part and India had started moving northwards. Finally it had collided with Asia about 40 billion years ago. The mountain range grew rapidly and it's still growing today. The continued growth in the Himalayas is due to the Indian tectonic plate still moving slowly but surely northward. We know this due to frequent earthquakes in the region.
