They may be huge continental ice sheets or small alpine (mountain) glaciers. Hurricanes and other extreme storms generate storm surge and large waves, eroding the beach and dune system and reshaping the coastal landscape. During the most extreme events, changes can occur across the width of an entire barrier island.

The Great Lakes. The Great Lakes are a prominent geologic feature of the Midwest and include three of the five largest lakes in the world: Lake Superior, Lake Michigan, and Lake Huron. In fact, the Great Lakes contain 21% of the world’s fresh water. A mere 20,000 years ago, the Great Lakes did not exist.Wind erosion produces sand blasting of surfaces and produces desert pavement, ventifacts, and desert varnish. Sand dunes are some of the most common wind born deposits, which come in many different shapes and sizes. Loess is a very fine grained, wind borne deposit that is important to soil formation in many regions.The grinding and wearing down of rock surfaces by other rock or sand particles is called abrasion. Abrasion commonly happens in areas where there are strong winds, loose sand, and soft rocks. The blowing of millions of sharp sand grains creates a sandblasting effect. This effect helps to erode, smooth, and polish rocks.These are called sand dunes (Fig. 3.9). When the grains of sand are very fine and light, the wind can carry it over very long distances. When such sand is deposited in large areas, it is called loess. Large deposits of loess is Fig. 3.9: Sand Dunes found in China. Exercises 1. Answer the following questions.

Sand dunes are some of the most common wind born deposits, which come in many different shapes and sizes. Loess is a very fine grained, wind borne deposit that is important to soil formation in many regions.

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.Glaciers, Deserts & Wind, Oceans & Shorelines. Terms in this set (224) ... The line separating areas where snow, deposited during the winter, disappears during the summer from those areas where the snow remains throughout the year. Alpine or Valley Glacier. form on mountain summits and flow downslope, following former stream valleys. ...The river that drained from Lake Agassiz is called the Glacial River Warren. It flowed over the top of a recessional moraine at Browns Valley. As the water eroded away the glacial deposits, the level in the lake dropped. Eventually enough large boulders were left behind that a boulder pavement was produced, which inhibited further downward cutting. How Glaciers Move. The movement of glaciers is referred to as flow, and it happens in two ways. 1. Plastic flow —involves movement within the ice. 2. Basal slip —slipping and sliding downward due to gravity. • The glacial budget is the balance, or lack of balance, between accumulation at the upper end of a glacier and loss, or wastage, at ...Loess - wind-blown silt deposits common along the Mississippi River Valley; Erosional Features. Ventifacts are geomorphic features made of rocks that are abraded, pitted, etched, grooved, or polished by wind-driven sand or ice crystals. They are most typically found in arid environments with little vegetation to interfere with these erosive ...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.Longitudinal dunes (also called Seif dunes, after the Arabic word for “sword”), elongate parallel to the prevailing wind, possibly caused by a larger dune having its smaller sides blown away. Seif dunes are sharp-crested and are common in the Sahara. They range up to 300 m (980 ft) in height and 300 km (190 mi) in length.In geography, a glacial deposit is a glacial landform, created by big rock or stones …The perched dunes of the Sleeping Bear Plateau are actually a relatively thin blanket of wind-blown sand resting on a thick deposit of sandy glacial debris. When the wind reworks the upper layers of glacial sediment, sand is deposited into dunes while the coarser material remains behind as a lag gravel.
