Glacial deposits are called till. Wind deposits are referred to as aeolian deposits and include loess, dunes, and hills.
The three forms of erosion are water, wind, and ice. Water erosion occurs through the movement of water, wind erosion happens when wind carries and deposits sediment, and ice erosion is when glaciers or ice sheets move and reshape the landscape.
Sand dunes and loess deposits are two types of deposits formed by wind erosion and deposition. Sand dunes are hills of sand that form in areas with strong winds, while loess deposits are fine, wind-blown sediment that accumulates over time to create thick layers of fertile soil.
Glaciers, waves, wind, and streams are all natural forces that shape and alter the Earth's landscape. They each transport materials—glaciers move ice and sediment, waves carry sediment along coastlines, wind erodes and deposits particles, and streams flow with water and debris. Additionally, all four processes are driven by energy: glaciers by gravity, waves by wind energy, wind by atmospheric pressure differences, and streams by gravity and topography. Collectively, they contribute to erosion, deposition, and the continuous transformation of ecosystems.
till is the name of the material. In most cases all glacial-related deposits are unsorted and unstratified.
Loess is a fine-grained, wind-blown sediment that can accumulate near glaciers due to the processes of glacial erosion and deposition. As glaciers advance and retreat, they grind down rocks into silt-sized particles, which can then be carried away by wind once the glacier retreats. This wind can deposit the silt in areas adjacent to the glacier, creating loess deposits. Additionally, the cold, dry conditions around glaciers can facilitate the formation and preservation of loess.
The types of wind deposits include dunes, loess deposits, and sand sheets. Dunes are mounds of sand shaped by wind, while loess deposits consist of fine-grained sediment deposited by wind. Sand sheets are large areas covered with wind-blown sand.
Glaciers and wind both contribute to the formation of loess deposits through their processes of erosion and sediment transport. Glaciers grind and pulverize rock material into fine particles as they move, which can later be deposited as glacial till when they melt. Wind then picks up these fine sediments, transporting them over long distances and depositing them in areas where the air currents slow down, forming loess deposits. This combination of glacial action and wind erosion creates the rich, fertile soils characteristic of loess regions.

till is the name of the material. In most cases all glacial-related deposits are unsorted and unstratified.
Four types of erosion are water erosion (caused by flowing water), wind erosion (caused by the action of wind), glacial erosion (caused by moving glaciers), and gravitational erosion (caused by gravity pulling material downhill).
