Geomorph

Question 1

occur where basins have been excavated by moving ice or where drainage patterns have been altered by deposition of glacial till.

Answer 1

Glacial Lakes

Question 2

When a linear mountain range has several closely spaced valleys, the alluvial fans may coalesce to form a gentle undulated slope on the sides of the bounding lowlands.

Playa lakes

Question 5

Steep sided hills that rise above a surrounding relatively flat plain.

Answer 5

movement due to gravitational pull.

Question 16

long parallel scratches and grooves that are produced by rocks embedded in the ice scraping against the rock underlying the glacier.

Answer 16

Glacier striations

Question 17

rock that has a smooth surface produced as a result of fined grained material embedded in the glacier acting like sandpaper on the underlying surface.

Answer 17

Glacial Polish

Question 18

If two adjacent valleys are filled with glacial ice, the ridges between the valleys can be carved into a sharp knife-edge ridge, called an

Answer 18

Arête

Question 19

Where three or more cirques are carved out of a mountain, they can
produce a sharp peak

Answer 19

Horn

bedrock knobs carved by glaciers into streamlined hills. One side is smoothened while the steep side is plucked.

Answer 20

Rouche Montoneé (Sheepback)

Question 21

nonsorted glacial drift deposited directly from ice

Answer 21

Till

Question 22

a glacially deposited rock or fragment that now rests on a surface made of different
rock

Answer 22

Erratics

Question 23

are deposits of till that have a form different from the underlying bedrock

Answer 23

Moraines

Question 24

long sinuous ridges of sediment deposited by streams than ran under or within a glacier

Answer 24

Eskers

Question 25

If depressions form underneath a glacier and remain after the glacier is melted then water filling these depressions become small lakes where fine-grained sediment is deposited.

Answer 25

Kettle Lakes

Question 26

Streams and lakes forming on top of stagnant ice may deposit stratified sediment on top of the glacier. When the glacier melts these deposits are set down on the ground surface. The former lake deposits become _____, and the former stream deposits become ________.

Answer 26

Kames and Kame Terraces

Answer 29

Glacial drift

Question 30

are streamlined asymmetrical hills composed of till

Answer 30

Drumlins

Question 31

Earlier glaciations are indicated by deposits called ____, a sedimentary rock formed when glacial till becomes lithified.

Answer 31

tillite

Solitary sand dunes shaped like crescents and with their tips pointing downwind

Answer 32

Barchan dunes

Question 33
