Sagot :

If the 2 plates carrying oceanic crust collide, one goes underneath the other causing a tsunami or or an underwater earthquake

If the 2 plates carrying continental crust collide, the collision squeezes the crust into mountain ranges

When a plate carrying oceanic crust collides with a plate carrying continental crust the denser oceanic plate subducts below the continental plate

Oceanic crust is the lithosphere layer that is found under the water or seas while continental crust shows the rocks which form the continents.

a. In case of collision of two plates and both are carrying oceanic crust then there would be the possibility of one crust would go under the other one. It means the crust that would be dense would be seen as sinking below the less dense crust. Thus, it may lead to a trench such as an earthquake in the ocean may occur or any islands may be formed.  

b. When there is a collision of two plates that are having continental crust then there would be a formation of mountain ranges as well as volcannos. It is because the collision would squeeze the crust into it.  

c. In the situation of collision between one plate with oceanic crust and the other with a continental crust plate then it would make the denser plate, which is the oceanic plate move under the less dense one that is the continental plate.  Thus, it may even lead to mid-ocean ridges.
