When the crust thickens, the elevation typically increases due to the isostatic response of the Earth's lithosphere. As the crust becomes more buoyant, it can rise to maintain equilibrium with the underlying mantle. This process is often associated with tectonic activity, such as mountain building or volcanic activity, which can further contribute to increased elevation. Overall, thicker crust generally leads to higher elevations.
tectonic plates
Continental crust is generally thicker and less dense than oceanic crust, which causes it to sit higher on the mantle. The composition of continental crust includes lighter, granitic rocks, while oceanic crust is primarily composed of denser basaltic rocks. This difference in density and thickness leads to the buoyancy of continental crust, resulting in its higher elevation compared to oceanic crust.
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.

?
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.

Mountain building
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.

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