Geological Processes Overview
Geological processes can be broadly grouped into five consisories: tectonic activity, erosion, weathering, wulcan, and sedimentation. Each process operates at different scales and rates, but they ary all courn by the Earth 's internal heat ande thee external energy from the sun and gragy. Thee following g liss providevides a brief description of each:

Tese processes do not t operate in izolation. For instance, tectonic upfilt exposes rocks to weathering, which then sumlies sediment to rivers, which ch deposit that sediment in deltas, which ph later may be buried and lithified, only ty be re- exposhed by further upflt and erosion - a continues cycle that has been shaping thee Earth for over four four billion years.
Tectonic Activity andd Landforms
Tectonic activity is the primary engine of large- scale landform development. Thee Earth 's lithosphere is divided into several rigid plates that relative te one anotherr at speeds of a few centieters per year - broughly the rate of fingernail growth. The interactions at plate boundaries produce different landforms:

On land, divergent boundaries create rift valleys (e.g., thee Eass African Rift Valley) with steep walls and volteric activity.

Earthquakes andLandscape Change
Earthquakes are sudden releases of elastic strain along faults. While they lass only seconds, they can dramatically alter landscapes. Large gerakes can trigger landslides that reshape hillside, cause rivers to change course, andd generate tsunami that erode coastrides.

Erosion andWeathering
Podczas gdy tektonik aktywity buduje ulgi dla, erosion and weathering work to tear it down. Tese two processes are intimately linked: weathering diintegrates rock into smaller particles, and erosion transports tim way. Thee rate of erosion depends on climate, rock type, slope, and the presence of vegetation.
