Question: 1 / 400

Define the concept of isostasy in geology.

The process of sedimentary layer formation

The balance between the Earth's crust and mantle

Isostasy refers to the equilibrium that exists between parts of the Earth's crust, which floats on the denser, underlying mantle. This balance is crucial to understanding how geological features and landforms adjust over time due to forces such as erosion, sediment deposition, and tectonic activity. The principle of isostasy explains how mountains can maintain their elevations despite the forces acting upon them, as their roots extend deep into the mantle to balance the weight above.

Other options do not align with the concept of isostasy; the process of sedimentary layer formation pertains more to lithification and sedimentation, the movement of tectonic plates involves dynamic interactions of the Earth's lithosphere, and the transformation of igneous rocks refers to processes like weathering or metamorphism.
