Geological Concepts

Front

Topography

Back

variations in elevation's of the crust

Front

Isostasy

Back

The equilibrium between continental crust and the denser mantle below it. Gravity balanced by buoyancy

Front

Mountain Root

Back

The part of a mountain that extends into the mantle, providing stability.

Front

Isostatic Rebound

Back

The rise of land masses after the lifting of a huge weight

Front

Orogeny

Back

The process of mountain formation, especially by the folding and faulting of the earth's crust.

Front

Compressive Forces

Back

Forces that squeeze the crust, leading to the formation of mountains and other geological features.

Front

Uplifted Mountains

Back

Mountains that have been raised by tectonic forces. Possibly due to buoyancy from less dense magma boiling up.

Front

Plateau

Back

Regional uplift with a flat-topped area

Front

Fault-block Mountains

Back

Mountains formed by stretching the earth's crust, pushing blocks downward.
