Which of the following occurs when mountain belts are eroded?

A) erosion is accompanied by isostatic rebound
B) the continental crust becomes thinner
C) deep metamorphic and plutonic rocks can be uplifted to the surface
D) all of these

Isostatic Rebound

The rise of land masses that were depressed by the weight of ice sheets during glaciation, occurring as the ice melts and the land slowly returns to its original elevation.

Metamorphic Rocks

Rocks that have been transformed by heat, pressure, or chemically active fluids, altering their original composition or structure.

Plutonic Rocks

Intrusive igneous rocks that crystallize deep underground from magma, such as granite and diorite.
