geology
Also known as: exogenetic phenomenon
Quick Summary
Exogenic phenomena in geology refer to processes that occur on or near the Earth's surface, driven by external forces like solar energy and gravity. These processes are primarily responsible for shaping the Earth's landforms through erosion and weathering.12
Key exogenic processes include:
- Water Erosion: Moving water, from rainfall to rivers and oceans, is a major agent of erosion, carrying away soil and rock debris.23
- Wind Erosion: Wind transports loose particles, especially in arid regions, leading to deflation and sandblasting.23
- Glacial Erosion: Ice sheets and glaciers abrade and pluck rock material as they move.2
- Mass Movement: Gravity causes soil and rock to move downslope, including soil creep, mudflows, and landslides.3
Organisms also contribute to landforms through biogenic processes, such as the creation of coral reefs or termite mounds, and human activities like construction and resource extraction significantly alter topography.4
