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 some ...
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.
A kame delta (or ice-contact delta, morainic delta [1]) is a glacial landform formed by a stream of melt water flowing through or around a glacier and depositing material, known as kame (stratified sequence of sediments) deposits.
Tunnel valley – Glacial-formed geographic feature; Turlough – Type of seasonal or periodic lake found in limestone areas of Ireland; Tuya – Flat-topped, steep-sided volcano formed when lava erupts through a thick glacier or ice sheet; U-shaped valley – Valleys formed by glacial scouring; Uvala – Toponym for a closed karst depression
In geography, a glacial deposit is a glacial landform, composed of sediments of varying size, from clay through sand to boulders, deposited in the landscape when the glacier withdraws. Subcategories This category has the following 3 subcategories, out of 3 total.
A kame, or knob, is a glacial landform, an irregularly shaped hill or mound composed of sand, gravel and till that accumulates in a depression on a retreating glacier, and is then deposited on the land surface with further melting of the glacier.
Till is a form of glacial drift, which is rock material transported by a glacier and deposited directly from the ice or from running water emerging from the ice. [1] It is distinguished from other forms of drift in that it is deposited directly by glaciers without being reworked by meltwater.
When the stream or rivers are associated with glaciers, ice sheets, or ice caps, the term glaciofluvial or fluvioglacial is used, as in periglacial flows and glacial lake outburst floods. [1] [2] Fluvial sediment processes include the motion of sediment and erosion or deposition on the river bed. [3] [4]
