Answer:
Convergent plate boundary is the boundary where two plates collide into each other. At those boundaries volcanic arcs and submarine volcanoes can be formed.
Explanation:
There are three types of convergent plate boundary:
1. <em>Oceanic-oceanic convergence</em>
That is the boundary where two oceanic plates collide. The one which is cooler and denser slides beneath another one. Example is Pacific and Mariana plates.
2. <em>Oceanic-continetal convergence</em>
That is the boundary where oceanic and continental plates collide. Oceanic plate is denser and it always slides beneath the continental. Good example is Pacific and South American Plate.
3. <em>Continental-continental convergence</em>
This is the boundary where two continental plates collide. This phenomenom is known as continental collision. very best example is collision of Eurasian and Indian plate.
At first and secound boundary types both volcanic arcs and submarine volcanoes can be formed. On contrary, third type is not related with volcanic formations, but only with seismic activity (earthquakes).
