PLANET Firn and ne’ve’ are repeated melting and refreezing forms of granules Background info 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.

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

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

What is meant by dissolution? Dissolution is the action of being dissolved. 3. What kinds of rock are most susceptible to solution processes? Why? Limestone and dolomite are most susceptible to solution processes because the water‚ which is slightly acidic

Desert and glacier landscapes contrast and formation process. Desert are created via natural ways‚ through climate changes and natural erosion‚ the wind blowing in those areas carries little or no moisture‚ bringing only fog and mist but no rains also those winds pick up and carry rock particles and those‚ will erode the ground and or the other rocks creating furthermore erosions‚ those desert’s also are the result of human activities such as deforestation‚ when humans deplete an area of the fragile

Erik M ENG 102 – 32816 8 Oct. 2008 Climate Change’s Effects on Glacial Melting On the sheltered slopes of the highest peaks in Glacier National Park‚ in Montana‚ the beautiful and majestic landmasses known as glaciers are quickly melting away. These giant landmasses are found all over the world‚ on both North and South Poles‚ on all seven continents‚ and even on the high peaks in the tropical regions near the equator. Over the past few decades‚ the global climate has been subject to vast changes

Glaciers have formed nature’s most attractive scenery on this earth. They are enormous icy rivers that often run thousands of feet deep and wide and will run for many miles in length. They cover huge amounts of land and can change land into beautiful mountains with many different features. Glaciers are one of nature’s most powerful forces and have a very slow process. One area where glaciers have been the most notable has been in Yosemite National Park in California. There we can see many glacial

Why are glaciers receding and what is the human impact? Glaciers although very impressive to look at‚ actually do have a purpose within our environment. Although many people believe that glaciers are not necessary‚ they already have been formed and without them it will have a serious impact on environment. Many people fear that without glaciers sea levels will rise‚ ultimately drowning various land masses and consuming certain areas all over the globe. Within my paper I will be discussing what a
