Answer:
The geological process taking place in the convergent boundaries is what is called subduction.
Explanation:
The tectonic plates moves from side to another and they are forced to sink because of substantial gravitational forces to the mantle.
The crust of the earth is continuous however it is divided into pieces, the pieces, therefore, is one called tectonic plates, and they move close to each other through the power of convection cycles contained in the mantle below the crust enabling the plates to move freely.
