Landforms related to rivers and other watercourses include: Channel (geography) – Narrow body of water; Confluence – Meeting of two or more bodies of flowing water; Cut bank – Outside bank of a water channel, which is continually undergoing erosion; Crevasse splay – Sediment deposited on a floodplain by a stream which breaks its levees
Later, when the glaciers retreated leaving behind their freight of crushed rock and sand (glacial drift), they created characteristic depositional landforms. Depositional landforms are often made of glacial till , which is composed of unsorted sediments (some quite large, others small) that were eroded, carried, and deposited by the glacier ...
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 Earth and on other ...
The word kame is a variant of comb (kame, or kaim is the Old Scottish word meaning 'comb'), which has the meaning "crest" among others. [2] The geological term was introduced by Thomas Jamieson in 1874. [3] According to White, "kames were formed by meltwater which deposited more or less washed material at irregular places in and along melting ice.
A diagram of various depositional environments. In geology, depositional environment or sedimentary environment describes the combination of physical, chemical, and biological processes associated with the deposition of a particular type of sediment and, therefore, the rock types that will be formed after lithification, if the sediment is preserved in the rock record.
The Irish word was and is used particularly to describe long sinuous ridges, which are now known to be deposits of fluvio-glacial material. The best-known example of such an eiscir is the Eiscir Riada , which runs nearly the whole width of Ireland from Dublin to Galway , a distance of 200 km (120 mi), and is still closely followed by the main ...
Subglacial meltwater is the main product of glacial ablation.This meltwater acts as the force that causes subglacial tills to deform, and also plays a significant role in shaping the morphology and distribution of the till on the till plain.
These fan-shaped deposits form by the deposition of sediment within a stream onto flat land at the base of a mountain. [1] The usage of the term in landscape description or geomorphology derives from the Spanish word bajada , generally having the sense of "descent" or "inclination".
