List four effects of Ice Age glaciers aside from the formation of major erosional and depositional features. 14) T F Every atom in nature has an identical spectrum, but when they combine into molecules, a unique spectrum is formed. - Drumlins, Eskers, Kames, Kettle Holes. A) The Earth wobbles on its axis. Eskers. ... Do the Quizlet. The drumlins are related on a regional scale to even larger landforms. (b) A drumlin is an asymmetrical hill made of sediments that points in the direction the ice moved. Kettles. 11) T F Eskers, moraines, and crevasses are all features that are associated with glaciers. Now match the features above with the letters in the drawing above. The Earth is expected to go back into a period of glaciation over the next _____ years. Drumlins are elongated hills of glacial deposits. Kames may be cone […] running along a glacier in a till plain. eskers drumlins. Eskers may range from 16 to 160 feet (5 to 50 m) in height, from 160 to 1,600 feet (500 m) in width, and a few hundred feet to tens of miles in length. 14. Kame Terraces. They can be 1 km long and 500 metres wide, often occurring in groups. 100 1,000 10,000 100,000. Drumlins and drumlin clusters are glacial landforms composed primarily of glacial till. A map of individual drumlins shows that features of similar form occur together. They form near the margin of glacial systems, and within zones of fast flow deep within ice sheets , and are commonly found with other major glacially-formed features (including tunnel valleys , eskers , scours, and exposed bedrock erosion ). Esker. The long axis of the drumlin indicates the direction in which the glacier was moving. Drumlin Which of the following would be best for a sand and gravel pit? Approximately how thick was the ice cap that covered northern North America during the last ice age? Winding ridge of un-assorted depositions of rock, gravel, clay etc. A) Cirques B) Drumlins C) Eskers D) Moraines 16) 17) Which of the following glacial features would typically be found in close proximity to each other? Drumlins. Eskers come in all sizes: ridges snaking across the countryside ranging from a few hundred feet to several miles long, and up to 50 or 100 feet high. - Large amount of the water trapped by the glaciers from the water cycle. d. Relate the past and present actions of ice, wind, and water to landform distribution and landscape evolution. The eskers resemble the features of an embankment and are often used for making roads. Esker, a long, narrow, winding ridge composed of stratified sand and gravel deposited by a subglacial or englacial meltwater stream. They may occur 13) T F Water erosion tends to wear away rough surfaces, leaving rocks that are usually smooth and rounded. Broken ridges or un-assorted depositions looking like hump in a till plain. Moraines. The name is derived from the Gaelic word druim (“rounded hill,” or “mound”) and first appeared in 1833. Eskers and kames are among the best-known of the various features formed by glaciers and by the running water associated with melting glaciers. ... c. Describe the processes and hazards associated with both sudden and gradual mass wasting. 15. (a) An esker is a winding ridge of sand and gravel deposited under a glacier by a stream of meltwater. Drumlins are generally found in broad lowland regions, Usually drumlins are found in groups called drumlin fields. Changes to the valleys and rivers are contributed by the glaciers, obliterating the former valleys and streams. arete kame varve a drumlin. A) esker B) lateral moraine C) kame D) unstratified till E) outwash plain Answer: B 9) Unfrozen ground in a region of discontinuous permafrost is known as A) nunatak B) talik C) patterned ground D) cryotic zone Answer: B 10) Which of the following is true? Drumlin, oval or elongated hill believed to have been formed by the streamlined movement of glacial ice sheets across rock debris, or till. 12) T F The lunar highlands are older than the lunar maria. List four depositional features other than moraines. These would have been part of the debris that was carried along and then accumulated under the ancient glacier.
