- One of three distinct processes involved in erosion. It is the movement of eroded material in the medium of air, water or ice.
- Geologic period that occurred roughly 1.6 to 65 million years ago. During this period, mammals become a dominant species on the planet.
- Layer of unconsolidated material found at the Earth's surface that has been influenced by the soil forming factors: climate, relief, parent material, time, and organisms. Soil normally consists of weathered mineral particles, dead and living organic matter, air space, and the soil solution.
- The range of topographic elevation within a specific area.
- Geologic period that occurred roughly 1.6 million years ago to today. During much of this period continental glaciers in the Northern Hemisphere covered large regions of land surface in the high and mid-latitudes. Homo sapiens appear about 200,000 years BP (before present) and become the first species to alter the Earth's environment on a large-scale.
- Erosive process of particle detachment by moving glacial ice. In this process, basal ice freezes in rock surface cracks. As the main body of the glacial ice moves material around the ice in the cracks is pulled and plucked out. Also called plucking.
- A term used in geography that describes the factors that make the location of natural and human-made phenomena unique.
A term used in geography that deals with the relative and absolution spatial position of natural and human-made phenomena.
Inundation of a land surface that is not normally submerged by water from quick change in the level of a water body like a lake, stream, or ocean.
Saddle like depression found between two mountain peaks. Formed when two opposing cirque glaciers back erode an arête.
General pattern of weather conditions for a region over a long period time (at least 30 years).
Process of grouping things into categories.
A body of sheltered water found in a crescent shaped coastal configuration of land.
