Converge is a large word that scientists use to describe two objects that come together. In the case of plate tectonics, the two objects coming together are large plate-like pieces of the Earth’s crust. As these two plates push against each other, one is ultimately forced down beneath the other.
When this happens near land, we see the earth above the two meeting plates rise, forming spectacular mountain ranges. A parallel oceanic trench typically forms just off the shore, as one plate descends deep into the Earth’s core.
These convergent boundaries commonly cause volcanoes to form, as old crust melts. As two plates rub against one another, a number of small and large earthquakes are common near convergent boundaries.
