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.

What happens to the leading edges of convergent plates as they collide?

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.


Is continental crust made of rocks such as granite?

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.
