There are times when there are more than two tectonic plates that collide in this area. If these two plates are of the same density, they would push against each other. This helps form a mountain. This also explains why most of the examples of convergent boundaries are located near the mountainside. One notable example is South America’s west coast.
There are a lot of mountains that were formed because of this but it is not only mountains that convergent boundaries can make. There are times when they can also form islands. The number of islands of the world is always changing because of the differences that occur in the world every day.
