Unconstrained these glaciers cover vast areas. Topography does not play a major role in the extent of these glaciers. Ice sheets and ice caps fall into the same category. The difference between them is one of scale. Ice sheets are larger. Typically the dividing line is around 50‚000 km2. The glaciers that cover Antarctica and Greenland are ice sheets‚ and the glacier that covers Iceland is an ice cap. Two main components of ice sheets and ice caps are ice domes and outlet glacier.

Glaciers We are all familiar with rivers. Rivers collect water and allow it to flow downhill. A glacier is like a river‚ but it a large slow-moving river of ice‚ formed from compacted layers of snow that has basically accumulated for more that a year‚ which slowly deforms and flows in response to gravity and high pressure. The first year of snow fall is called a neve‚ then after the snow stay for more that one winter it’s called a firn. (Grabianowski). Extensive glaciers can be found

Glaciers are present year-round‚ but vary in their rate of melting. For a pack of ice to qualify as a glacier‚ it exist continually rather than just seasonally. For reasons that are not completely clear‚ the planet has experienced several major Ice Ages in its history‚ when glaciers extended as far south as New York‚ USA and Paris‚ France. So many glaciers piled up that the sea level was lowered by 100 m (328 ft)‚ opening up large areas of land such as the North Sea‚ the Bering strait‚ and connecting

Siachen Glacier The Siachen Glacier is located in the East Karakoram Himalaya‚ at approximately 35.5° N 76.9° E. It is one of the five largest glaciers in the Karakoram‚ situated at an average altitude of 5‚400 meters above sea level. Most of the Siachen Glacier is a hotly contested territory between Pakistan and India. The Siachen glacier lies south of the great watershed that separates Central Asia from the Indian subcontinent‚ and Pakistan from China in this region. The 78 km long Siachen glacier

Shrinking Glaciers 4/10/12 As a direct result of anthropogenic induced climate change there have been a number of observed changes to our environment and potential hazards created that threaten our planet. Along with increased storm frequency‚ abnormal precipitation patterns‚ and increasing sea levels that grab the headlines in the news‚ a very critical issue is threatening mountain communities across the globe. With each subsequent year global mean temperatures rise‚ mountain glaciers are shrinking2

1. Geological Features: A glacier is commonly white and made of ice. It may appear dirty near its end due to debris that it is carried or pushed by the movement of the glacier. Glaciers can be massive in size stretching across continents (Greenland) or may be small sitting atop of mountains. a. landscape is ice with some formation of dirt and other land mixed in due to movement. b. the size of a glacier may depend on if on land or broken off from land.

Hoeung 1 Tiffany Hoeung Ms. Braceras Honors Earth Science 4 March 2015 How Does Slope Affect the Movement of a Glacier Purpose: The purpose of this lab was to find how slope would affect glacier’s movement‚ and whether the movement was at a constant rate or changed. Hypothesis: If the slope is more steep‚ then the glacier’s movements will be faster than a less steep slope. Materials: Flubber Glue Water Borax Long tray Timer Procedure: 1
