  2. Glacial landform - Wikipedia

    en.wikipedia.org/wiki/Glacial_landform

    Erosional landforms. As the glaciers expand, due to their accumulating weight of snow and ice they crush, abrade, and scour surfaces such as rocks and bedrock.The resulting erosional landforms include striations, cirques, glacial horns, arêtes, trim lines, U-shaped valleys, roches moutonnées, overdeepenings and hanging valleys.

  3. Fluvioglacial landform - Wikipedia

    en.wikipedia.org/wiki/Fluvioglacial_landform

    Fluvioglacial landforms or glaciofluvial landforms[a] are those that result from the associated erosion and deposition of sediments caused by glacial meltwater. Glaciers contain suspended sediment loads, much of which is initially picked up from the underlying landmass. Landforms are shaped by glacial erosion through processes such as glacial ...

  4. Aeolian processes - Wikipedia

    en.wikipedia.org/wiki/Aeolian_processes

    Wind erosion of soil at the foot of Chimborazo, Ecuador Rock carved by drifting sand below Fortification Rock in Arizona (Photo by Timothy H. O'Sullivan, USGS, 1871). Aeolian processes, also spelled eolian, [1] pertain to wind activity in the study of geology and weather and specifically to the wind's ability to shape the surface of the Earth (or other planets).

  5. Drumlin - Wikipedia

    en.wikipedia.org/wiki/Drumlin

    A hypothesis that catastrophic sub-glacial floods form drumlins by deposition or erosion challenges conventional explanations for drumlins. [20] It includes deposition of glaciofluvial sediment in cavities scoured into a glacier bed by subglacial meltwater, and remnant ridges left behind by erosion of soft sediment or hard rock by turbulent ...

  6. Outwash plain - Wikipedia

    en.wikipedia.org/wiki/Outwash_plain

    An outwash plain, also called a sandur (plural: sandurs[1]), sandr[2] or sandar, [3] is a plain formed of glaciofluvial deposits due to meltwater outwash at the terminus of a glacier. As it flows, the glacier grinds the underlying rock surface and carries the debris along. The meltwater at the snout of the glacier deposits its load of sediment ...

  7. Geomorphology - Wikipedia

    en.wikipedia.org/wiki/Geomorphology

    Geomorphology (from Ancient Greek: γῆ, gê, 'earth'; μορφή, morphḗ, 'form'; and λόγος, lógos, 'study') [2] is the scientific study of the origin and evolution of topographic and bathymetric features generated by physical, chemical or biological processes operating at or near Earth's surface. Geomorphologists seek to understand ...

  8. Aeolian landform - Wikipedia

    en.wikipedia.org/wiki/Aeolian_landform

    Aeolian landform. Aeolian landforms, or Eolian landforms, are produced by either the erosive or depositive action of wind. These features may be built up from sand or snow, [1] or eroded into rock, snow, or ice. Aeolian landforms are commonly observed in sandy deserts and on frozen lakes or sea ice and have been observed and studied around ...

  9. Pyramidal peak - Wikipedia

    en.wikipedia.org/wiki/Pyramidal_peak

    Pyramidal peak. The Matterhorn, a classic example of a pyramidal peak. A pyramidal peak, sometimes called a glacial horn in extreme cases, is an angular, sharply pointed mountain peak which results from the cirque erosion due to multiple glaciers diverging from a central point. Pyramidal peaks are often examples of nunataks.
