1 .		During the Ice Age, ice sheets and alpine glaciers were far more extensive than they are today.   True  False
2 .		Snow accumulation and glacial ice formation occur in an area known as the zone of wastage.   True  False
3 .		Lateral moraines are ridges of till paralleling the sides of a glaciated valley.   True  False
4 .		The two major types of glaciers are valley glaciers and ice sheets.   True  False
5 .		Under pressure equivalent to the weight of 10 meters of ice, ice will behave as a plastic and flow.   True  False
6 .		The Ice Age began between two and three million years ago.   True  False
7 .		Glaciers are a part of both the hydrologic cycle and the rock cycle.   True  False
8 .		The position of the front of a glacier depends on the balance between accumulation and wastage.   True  False
9 .		The combined areas of present-day continental ice sheets represents almost thirty percent of Earth's land area.   True  False
10 .		Today, the only ice sheets on Earth are in Greenland and Antarctica.   True  False
11 .		The outer limits of the zone of accumulation are defined by the snowline.   True  False
12 .		The rates that glaciers advance vary considerably from one glacier to another but can be as great as several kilometers per day.   True  False
13 .		The breaking off of large pieces of ice at the front of a glacier is a process called crevassing.   True  False
14 .		Glaciated valleys typically exhibit a V-shaped appearance.   True  False
15 .		The movement of glacial ice is generally referred to as flow.   True  False
16 .		Slightly more than 2 percent of the world's water is tied up in glaciers.   True  False
17 .		Streamlined asymmetrical hills composed of till that occur in clusters are called eskers.   True  False
18 .		Glaciers are capable of carrying huge blocks of material that no other erosional agent could possibly transport.   True  False
19 .		The Matterhorn in the Swiss Alps is the most famous example of a cirque.   True  False
20 .		Sediments laid down by glacial meltwater are called stratified drift.   True  False
21 .		Moraines are bowl-shaped erosional features found at the heads of glacial valleys.   True  False
22 .		In some regions of the United States that were once covered by Ice Age glaciers the crust is rebounding upward.   True  False
23 .		Moraines are composed of stratified drift.   True  False
24 .		Glaciers form in regions where precipitation is less than infiltration.   True  False
25 .		Fiords are deep, steep-sided ocean inlets formed by glacial erosion.   True  False
26 .		An individual boulder, different from the local bedrock, that was deposited by a glacier is called a glacial erratic.   True  False
27 .		Stratified drift is sorted sediment.   True  False
28 .		The extensive glaciations that have occurred on Earth may be related to plate tectonics.   True  False
29 .		Erosion by ice sheets tends to subdue the topography of a region.   True  False
30 .		Variations in Earth's orbit is one hypothesis for the cause of glacial ages.   True  False
