Generally, subduction zones are formed when two plates collide and one is heavier than the other. When two continents collide, rather than one sinking, they will both be uplifted because they are light and buoyant.
The Alps are a result of the collision between Africanand European tectonic plates, during which the western part of the Tethys Ocean, (which was formerly in between these continents), disappeared.
The oceanic crust is subducted underneath the continental crust. This process is known as subduction.
Dense oceanic crust slides under less dense continental crust
Earth Quakes are a given whenever two plates collide. That's the only thing I know in which happens during a collision. There might also be volcanic activity but I'm not sure.

At a convergence boundary during collision of two plates there could either be Subduction or Outcropping. Subduction occurs when the collision involves plates of different types and densities while the other happens when it involves similar plate types. Mountain ranges are formed, also Subduction Zones gives rise to Trenches.
The Alps are a result of the collision between Africanand European tectonic plates, during which the western part of the Tethys Ocean, (which was formerly in between these continents), disappeared.
The Cascade volcanoes were formed during the collision between the west moving North American plate and the east moving Juan de Fuca plate along the subduction zone that forms the boundary between the two plates
Mountain Range, example is the Himalayas Mountains in ASIA, formed from collision of Indian with Asia during its northward migration from Gondwanaland.
Elastic Collision is the collision in which colliding objects rebound without lasting deformation or heat generation.Inelastic collision is a collision in which the colliding objects become distorted and generate heat during collision and possibly stick together.

well i know momentum remains same before and after collision... But what about the period during which collision takes place?
During the high-speed collsision, the cars would cause more kinetic energy than with a low collision. It would cause damage because there is a greater amount of force exerted in the high-speed collision.
momentum
No loss in energy due to collision is for elastic collision. But there will be a loss during collision in case of in-elastic collision. So KE will remain constant before and after collision in case of elastic collision.
