Exam 14: Glacial and Periglacial Landforms

When intersecting cirques carve away the mountain, narrow, sharp ridges called what are formed?

The landform at A is a(n):

Define a cirque. Discuss how and where a cirque forms.

Where exposed cirques have intersected deeply, a notch is formed. This is called a/an:

A large, thick plate of glacial ice moving outwards in all directions is a(n):

Glacial ice makes the Earth's albedo lower.

Permafrost presently occurs in regions of Eurasia and North America even where glaciers are not currently found.

The last period of glacial advance began about 140,000 years ago.

Beyond the moraine, a smooth area of water-laid sediment often marked by kettles and kames, is called a/an:

A mixture of different sized rock fragments deposited by a glacier is BEST called:

Lakes that form in glaciated valleys are called trough lakes.

Sorted and layered materials deposited by a glacier are BEST called:

A deep, steep-sided rock trench formed by erosion from alpine glaciers is a(n):

No glaciers are located near the equator.

Glaciers usually result in areas of:

Describe the speed of ice movement across the surface of an alpine glacier. Clarify your description with an illustration, and explain the causes of this pattern.

A lake that forms in the depression at the bottom of a cirque of an alpine glacier is a(n):

Any large natural accumulation of land ice affected by present or past motion is a(n):

Sea ice is associated with:

On the illustration, the landform at E is a(n):
