Describe how the size of sediment particles effects their movement during deflation. The more energy that wind has, the larger particles of sediment it can move. In general, small, fine particles can be picked up and blown through the air.Glaciers are categorized by their morphology, thermal characteristics, and behavior. Alpine glaciers, also known as mountain glaciersor cirque glaciers, form on the crests and slopes of mountains.An alpine glacier that fills a valley is sometimes called a valley glacier.A large body of glacial ice astride a mountain, mountain range, or volcano is termed an ice cap …The term "glacial drift" applies to: a. glacial deposits of very fine particles that eventually become wind-blown. b. glacial deposits that are carried by meltwater into nearby streams. c. all glacial deposits, collectively. d. the redistribution of glacial deposits by consecutive advances. Knowledge of past changes in the Westerlies is important for understanding the climatic and environmental evolution of Central Asia. Here, we use high-resolution grain size records from several loess deposits in Central Asia to study the spatial pattern of the Westerlies during an interval of high global ice volume during the Last Glacial Maximum.Depositional landforms caused by wind are sand dunes, loess, barchan, seif, parabolic, transverse dunes, longitudinal dunes, etc. Wind-blown sediments are deposited as a result of a significant reduction in wind speed and obstruction caused by bushes, forests, marshes and swamps, lakes, large river walls, and so on.

The general name for any sediments transported and deposited by glacial ice is till. Subglacial sediment (e.g., lodgement till) is material that has been eroded from the rock underlying the glacier by the ice and then transported by the ice. It has a wide range ...This often happens when the wind has to move over, or around, an obstacle. A rock or tree may cause wind to slow down. As the wind slows, it deposits the largest particles first. Different types of deposits form depending on the size of the particles deposited. Deposition of Sand. When the wind deposits sand, it forms small hills of sand.Wind Wind has shaped this landscape next to the Platte River, near Grand Rapids, NE. Photo credit: Amber Anderson Loess.

The mineral constituents of loess (quartz and feldspar, for example) are reduced to minute particles by weathering action, principally in semiarid and arid regions. …For example, wind-blown sands are typically extremely well sorted, while glacial deposits are typically poorly sorted. These characteristics help identify the type of erosion process that occurred. Coarse-grained sediment and poorly sorted rocks are usually found nearer to the source of sediment, while fine sediments are carried farther away.Loess.
