Glacierized areas cover over 15,000,000 square kilometers. Antarctic ice is over 4,200 meters thick in some areas. In the United States, glaciers cover over 75,000 square kilometers, with most of the glaciers located in Alaska. During the last Ice Age, glaciers covered 32% of the total land area. If all land ice melted, sea level would rise approximately 70 meters worldwide. Glacier ice crystals can grow to be as large as baseballs. The land underneath parts of the West Antarctic Ice Sheet may be up to 2.5 kilometers below sea level, due to the weight of the ice. North America's longest glacier is the Bering Glacier in Alaska, measuring 204 kilometers long.

Glaciers Foreword Glacial Processes Glacial Landforms Illinois Glacial History Foreword In approximately 4.6 billion years of Earth history, there have been three major episodes of glaciation. The Varangian glaciation occurred during the Proterozoic part of the Precambrian period about 700 million years ago (m.y.a.). The next one happened in the late Paleozoic Era around 300 m.y.a. The most recent period of glaciation started approximately 1.6 m.y.a. and ended about 10,000 years ago. Today, glaciers contain nearly 75% of the world’s fresh water supply in ice that covers about 10% of land area. In contrast, ice covered as much as 30% of total land area during the most recent ice age. The largest concentration of ice today is the Antarctic ice sheet, up to 4,200 meters thick in some areas, and in the Greenland ice sheet. The remainder of glaciers is located in montane regions and in ice caps in polar seas. If climate were to suddenly warm enough to melt all land ice, there would be a eustatic sea level rise of about 70 meters. Sea level has risen about 100 meters since the last glacial maximum 20,000 years ago.

GLACIERS - FROM WIKIPEDIA A glacier is a large, slow moving river of ice, formed from compacted layers of snow, that slowly deforms and flows in response to gravity. RETREAT OF GLACIERS SINCE 1850 The retreat of glaciers, worldwide and rapid, affects the availability of fresh water for irrigation and domestic use, mountain recreation, animals and plants that depend on glacier-melt, and in the longer term, the level of the oceans.

Fabulous Glaciers What Happens Next? Life Around The Glacier The Big Shuffle High Elevation Homes Shhh, Pups Sleeping How To Enjoy The Glaciers How It All Started Glacier Heaven - Southeast Alaska A laska has hosted a glacier-favoring mixture of climate and topography for the last 12.5 million years. During the Pleistocene age, when the climate was 3 to 9 degrees Fahrenheit colder than it is today, an ice sheet covered a large expanse of the earth, including the islands of southeastern Alaska. Today there are still over 100,000 glaciers in Alaska, although ice covers only 5 percent of the state. The icefields and glaciers of the Tongass National Forest are some of the few remnants of the once-vast ice sheets. In Southeast Alaska, maritime climate and coastal mountains work together to create favorable conditions for glaciation. The icefields straddle the Coast Mountain Range on the United States-Canadian border, directly in the path of the Pacific Ocean's prevailing winds. Moist air flows toward the mountains, rises, cools, and releases snow and rain. Annual snowfall on the Juneau Icefield exceeds 100 feet, and mild Southeast summers assure that winter snow accumulation exceeds summer snowmelt at higher elevations.

8. Glaciers Easier glaciers are rivers of ice that move very slowly. They can take a year to move as far as you can walk in a few minutes. http://www.42explore.com/glaciers.htm

The Topic: Glaciers Easier - Glaciers are rivers of ice that move very slowly. They can take a year to move as far as you can walk in a few minutes. When a piece of a glacier breaks off and floats in the water, it's called an iceberg. Harder - Glaciers form high in mountain valleys (valley glaciers) and in polar regions (continental glaciers) where the snow falls but never melts. The heavy snow crushes the layers below and forms a mountain of ice. As the glacier moves slowly down the mountain, it grinds against the ground and the walls of the valley to make it deep and wide. Glaciers cover about six million square miles which is about three percent of the earth's surface.

12. Glacier Introduction glaciers are very extraordinary. They are large masses of ice that flow slowly over land in the polar regions and in some high mountain valley s. http://library.thinkquest.org/TQ0311164/home.htm

Continental Glaciers Valley Glaciers Glaciers are very extraordinary They are large masses of ice that flow slowly over land in the polar regions and in some high mountain valley s . They form where snow falls in the winter and doesn't melt away in the spring and summer. Every year new snow falls on top of last year's snow and ice making a new layer. After many years many different layers of snow and ice pack together and form a glacier. Glaciers flow down slopes in the ice fields and down mountain slopes because gravity pulls it downward until the land levels off or where the temperature is too warm to keep the snow and ice frozen. Photo courtesy of There are two kinds of glaciers, continental and valley glaciers. As glaciers are pulled downward by gravity they scrape across the land and damage it. With every winter season, glaciers grow larger as long as the temperature is cold enough to keep it frozen and if more snow falls. Site Outline Bibliography Glossary Activities

Glaciers and Glaciation Glaciers and the Hydrologic Cycle Glaciers are masses of ice that flow under the influence of gravity. The term glacier does not include icebergs, sea ice, or immobile snow fields in mountainous areas. Glaciers cover about 10% of the Earth's land surface, with the Greenland and Antarctica ice sheets accounting for about 96% of the land covered. Glaciers are the largest reservoir of fresh water and contain about 2.15% of the world's water. Mountain glaciers are found all over the world, even near the equator. Glacial ice eventually melts or vaporizes and returns to the hydrologic cycle. Origin of Glacial Ice Glacial ice forms by the recrystallization of snow. Ice is a mineral, and glacial ice is a rock. The conversion of snow to ice involves several steps: Accumulation of snow snowfields grow in areas above the snow line where more snow accumulates in the winter than melts during the summer. Freshly fallen snow has about 80% void space. Formation of ice granules - as snow accumulates and gets thicker

Often you'll see them bow riding or circling the boat at high speeds, breaking the water to breathe. Generally these 4- to 6- foot mammals travel in pairs or large groups. Steller's Sea Lions (Eumetopias jubatus) Likely to see on Kenai Fjords Half-Day and Full-Day cruises This rare, endangered species lives in large colonies, feeding largely on mollusks and fish. They grow to 6 to 8 feet and weigh 1,500 lbs. (males) and 600 lbs. (females). They are distinguished from their cousins, the California Sea Lion, by their light colored, reddish fur. Harbor Seals (Phoca vitulina) Likely to see on all cruises This wide-ranging seal can be found throughout most coastal waters in the northern latitudes. In Alaska, they are often seen resting on ice floes around the active glaciers. They grow to a length of 4 to 5 feet and weigh 250 lbs.
