Answer: Two colliding lithospheric plates make a convergent boundary.
Explanation: A convergent boundary is formed when two plates (lithosphere) move toward each other and collide. Lithospheric plates are those which form the lithosphere of the Earth. Convergent boundaries are also known as destructive boundaries.
Subduction refers to the sideways and downward movement of the edge of a plate of the earth's crust into the mantle beneath another plate.
There are three types of convergences:
1. Oceanic-oceanic convergence - In collisions between two oceanic plates, the cooler, denser oceanic lithosphere sinks beneath the warmer, less dense oceanic lithosphere.
2. Continental-oceanic convergence - When the oceanic lithosphere and continental lithosphere collide, the dense oceanic lithosphere subducts beneath the less dense continental lithosphere.
3. Continental-continental convergence - When two plates carrying continents collide, the continental crust buckles and rocks pile up, creating towering mountain ranges.
