Drumlins and eskers are found in glacial areas. Winding ridge of un-assorted depositions of rock, gravel, clay etc. - Large amount of the water trapped by the glaciers from the water cycle. Broken ridges or un-assorted depositions looking like hump in a till plain. Eskers on paleo-ice-sheet beds are more abundant in areas of crystalline bedrock with thin coverings of surficial sediment than in areas of thick deformable sediment e.g., 9,4.This is because meltwater flowing at the bed is more likely to incise upwards into the ice to form an R-channel where the bed is hard; where the bed is deformable, meltwater is more likely to incise downwards 10. The Irish word was and is used particularly to describe long sinuous ridges, which are now known to be deposits of fluvio-glacial material. These would have been part of the debris that was carried along and then accumulated under the ancient glacier. Some of the other features associated with glacier erosion in alpine regions are cirques, horns, and arêtes (Figure 10af-3). Kame Terraces. Which of the following features are typical of both alpine and continental glaciation ? Briefly describe the following glacial features associated with ice sheets: terminal moraine, kettle, drumlin, outwash plain, esker, and kame. Cirques are the bowl shaped depressions found at the head of glacial valleys. 22) comprise most of the area up-ice from the front of both lobes. b. 2-3.2 Glacial History In the last approximately one million years, there have been four glacial advances across central and eastern North America. running along a glacier in a till plain. The term esker is derived from the Irish word eiscir (Old Irish: escir), which means "ridge or elevation, especially one separating two plains or depressed surfaces". What typically happens to global sea level during an ice age? A) striations and erratics B) drumlins and cirques ... drumlins B) striations C) eskers D) kettles . Which features form by deposition from glacial meltwater? They vary in length from a fraction of a mile to scores of miles, and in height from a few feet up to several hundred and more feet. D 29 Which of the following features is a result of glacial deposition A) erratic B) arête C) cirque D) horn A 30 The long axis of a drumlin is aligned with the direction of glacier movement. Drumlins are hills made of glacial sediment and till, while eskers are long ridges of glacial drift. Most eskers are on till plains although some are known to cut through moraines and even cross drumlins. Esker. Eiscir) is one of the most striking landforms of fluvioglacial deposition. It increases. For most alpine glaciers, cirques are the areas in the alpine valleys where snow first accumulated and was modified into glacial ice. Briefly describe the following glacial features associated with mountain glaciers: cirque, arete, horn, hanging valley, lateral moraine, medial moraine. Drumlin 15. Esker: A long narrow ridge, often sinuous, composed of stratified sediment and marking the former location of a glacial tunnel. - Drumlins, Eskers, Kames, Kettle Holes. More than a thousand eskers have been found in Michigan. The long axis of the drumlin indicates the direction in which the glacier was moving. They can be 1 km long and 500 metres wide, often occurring in groups. List four effects of Ice Age glaciers aside from the formation of major erosional and depositional features. In low-lying, boggy terrain these snaking ridges dominate the terrain, providing vantage points and dry route ways. Drumlins are elongated hills of glacial deposits. 14. List four depositional features other than moraines. The esker (Ir. Ground moraine with drumlins and till-covered bedrock rises (Fig. It decreases.

Tarns, hanging valleys, and horns d. Roches moutonnées, arêtes, and fjords. These units are: ground moraine and drumlins, stratified drift, end moraine and stagnate-ice or dead-ice moraine, and special features such as moulin kames, eskers, and crevasse fills. a.
