This glossary of geography terms is a list of definitions of terms and concepts used in geography and related fields, including Earth science, oceanography, cartography, and human geography, as well as those describing spatial dimension, topographical features, natural resources, and the collection, analysis, and visualization of geographic ...
The process of determining a specific date (in years or some other unit of time) for an archaeological, geological or paleontological site or artifact. accident A sudden discontinuity of ground, such as a fault of great thickness, bed or lentil of unstable ground. [1] accretion A process by which material is added to a tectonic plate or ...
Chink, regional term in Central Asia for steep chalk and limestone escarpments and cliffs of height up to 350m, often around flat-top elevations; Cryoplanation terrace – Formation of plains, terraces and pediments in periglacial environments; Cuesta – Hill or ridge with a gentle slope on one side and a steep slope on the other
Thrust and reverse fault movement are an important component of mountain formation. Illustration of mountains that developed on a fold that thrusted.. Mountain formation occurs due to a variety of geological processes associated with large-scale movements of the Earth's crust (tectonic plates). [1]
The term "precession" typically refers only to this largest part of the motion; other changes in the alignment of Earth's axis—nutation and polar motion—are much smaller in magnitude. Earth's precession was historically called the precession of the equinoxes , because the equinoxes moved westward along the ecliptic relative to the fixed ...
Basal sliding is the act of a glacier sliding over the bed due to meltwater under the ice acting as a lubricant.This movement very much depends on the temperature of the area, the slope of the glacier, the bed roughness, the amount of meltwater from the glacier, and the glacier's size.
Frontogenesis is a meteorological process of tightening of horizontal temperature gradients to produce fronts. In the end, two types of fronts form: cold fronts and warm fronts. A cold front is a narrow line where temperature decreases rapidly.
The two main disciplines of geomechanics are soil mechanics and rock mechanics.Former deals with the soil behaviour from a small scale to a landslide scale. The latter deals with issues in geosciences related to rock mass characterization and rock mass mechanics, such as applied to petroleum, mining and civil engineering problems, such as borehole stability, tunnel design, rock breakage, slope ...
