When large ice sheets melt, the underlying crutt rebounds upward, a process still existring in Scandinavia andNorth America.

The Sierra Nevada in California Was uplifted primarily by normal faulting along its eastern escarpment. Such upfift creates steep, asymetrycal landscapes.

Geological andEcological Consequenceres

Soil Formation andErosion

Uplifted regions expose fresh rock to weathering. Over time, physical and chemical weathering breaks down rock into soil. The rate of soil formation depends on climate, rock type, and slope. In mountains areas, steep slopes akcelerate erosion, removing soil faster than can form. This creates thin, rocky soils on ridges and deeper soils in valleys.
