Rebound
This depends on what material (oceanic crust or continental crust) the leading edges are made of. When Continental crust hits Continental crust (eg India ploughing into Asia) the crust thickens by thrusting and folding and a mountain belt forms (the Himalayas). There is little or no volcanic activity associated with this sort of collision. When Oceanic crust meets Continental crust (eg the Pacific plate and the west coast of South America), the oceanic crust sinks below the continental crust forming an oceanic trench on the oceanic side (a subduction zone) and a mountain belt on the continental side (by folding and uplift). This sort of collision produces a large amount of volcanic activity. When Oceanic Crust meets Oceanic Crust, the actively spreading side sinks below the stationary side to form a back arc basin associated with island arcs and subduction zones (eg the Caribbean or the east of Papua New Guinea). This sort of collision also involves a large amount of volcanic activity.
An Earthquake
Yes, continental crust is primarily composed of granitic rocks such as granite. This type of rock is less dense than the basaltic rocks found in oceanic crust, which contributes to the higher elevation of continental landmasses.
It thickens and turns into a gel

tectonic plates
The Earth's oceanic crust is very thin at the mid-ocean ridges, and gradually thickens as it moves away from the ridges. The continental crust is thickest under mountain ranges. The average depth of oceanic crust is around 5 miles. The average depth of continental crust is 22 miles.
The highest point of the Earth's crust is to be found at the top of Mt. Everest which has an elevation of 8,848 metres.

it is called rebound.

it is called rebound.
Erosion happens in the earths crust and it happens because of that layer is exposed to that weather
