That which type of boundary do lithospheric plates collide

Answer

The type of boundary formed when lithospheric plates collide is called Convergent boundary

Explanation

When plates of the lithosphere collide, they form a sub-duction zone where the denser plate will be subdued underneath the less dense one. The one subdued later melts and get destroyed. This boundary occurs when; ocean crust meets ocean crust, when oceanic and continental crust meet and where continental crust meets continental crust.
