Exam 14: Glacial and Periglacial Landforms

Water is commonly found in pore spaces in the ground, and in its frozen state it is known as __________________________.

The rising of land areas in response to the disappearance of the weight of glacial ice is called:

Terminal and recessional moraines differ only in that the terminal moraine is located farthest from the source of the ice.

How are glaciers and ice sheet currently changing? Support your statement with several examples. Why is this occurring?

Since the Wisconsin Glaciation ended, the Earth has been in a period of interglaciation known as the _______________________________

When the amount of melting equals the amount of accumulation, the glacier is in equilibrium and is

Sharp ridges in between two corresponding cirques are known as __________________.

The grinding and scratching of rock fragments carried by a glacier against rocks or other fragments is called:

The last major glaciations era that occurred in North America was known as the _______________________.

Most deposition by glaciers occurs near the source of the ice.

Conditions that permit glacial formation include:

A glacier that forms in a mountainous area is called a(n):

Great plates of floating ice on a continental glacier are:

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

Continental glaciers have altered areas of both the middle latitudes and the subarctic.

Most of New England and the north central United States is covered by less than three meters of glacial drift.

Glacial advances raise sea level.

Alpine glaciers originate from a snowfield that has collected in a bowl-shaped depression called a:

We are currently in an interglacial period.

The ridge of material that collects at the farthest advance of the glacier is the:
