Glaciers


As many people hear the word glacier they immediately think about the Titanic and how it sank because it ran into a glacier. What many people do not know is the history of glaciers. There are a couple different types of glaciers, for instance the type that the titanic ran into is a Tidewater glacier, which is a glacier that flows in the sea. There are also alpine glaciers which are glaciers that are found in the mountains, and there are Continental glaciers which are associated with the ice ages, and that covers most of the contnents at one time; including Indiana. Glacier ice is the largest amount of fresh water in the world only second to the oceans as the largest reservoir of water total. Glaciers are found on every continent except Australia.

Glaciers are more or less permanent bodies of ice and compacted snow that have become deep enough and heavy enough to flow under their own weight. Glaciers require very specific climatic conditions. Glaciers develop where the temperatures are cold enough to allow the snow to accumulate and compacted. Most are found in regions of high snowfall in winter and cool temperatures in summer. These conditions ensure that the snow that accumulates in the winter isn't lost (by melt, evaporation, or calving) during the summer. Such conditions typically prevail in polar and high alpine regions. There are two main types of glaciers: valley glaciers and continental glaciers (Armstrong).

Essay on Glaciers as an Indicator of Climate Change

- Glaciers as an Indicator of Climate Change Introduction: It is now a well-documented scientific fact that both the 20th and 21st centuries have experienced a general trend in terms of global warming. Scientific research and evidence clearly indicate that the earth’s surface temperatures are gradually increasing. There have been a variety of theories pertaining to the fundamental causes of global warming. However, one of the outstanding beliefs is that human activities are distinctively responsible for global warming....   [tags: global warming, scientific research, evidence]

The Problems of Glaciers Melting Essay

- ... Satellite altimetry measures ice sheet volume changes from laser and or radar altimeters. This can be converted to changes in mass by accounting for spatially and temporally varying surface density distribution coupled with spatial exploration of unsampled regions. Limitations of this method, similar to other scientific methods lie in the models used. A second method used is referred to as input-minus-output. Through this method scientists calculate the difference between the snow mass accumulation and meltwater discharge resulting in a mass imbalance....   [tags: ice, water, level, sea]

Formation of the North Dakota Landscape Glaciers Essay

- Summary The objective of this study is to research how glaciers affected the North Dakota landscape in relation to photographs taken of North Dakota. In doing so one can come to understand the landscape that the citizens of North Dakota see everyday depending on what part of the state they are located. In doing research at the library and using educational internet sources the glacier that covered most of North Dakota some twenty thousand years ago affected the state in two different ways as the western side is part of the Great Plains region and eastern half is part of the Central lowland plains which have two different types of landscapes....   [tags: Grassy Butte, North Dakota]

The Glaciers of Yosemite National Park Essay

- The Glaciers of Yosemite National Park One of nature's most powerful and influential forces is also one of nature's coldest and slowest processes. These great icy rivers are called glaciers and have formed some of the most beautiful scenery on this planet. These enormous frozen bodies of water are often thousands of feet wide and deep and many miles long. They cover millions of acres of land and drastically change the land into beautiful mountains with many amazing features. One of the areas where glaciers have been most influential is in Yosemite National Park in California....   [tags: Geology]

Glaciers in Oregon and The Fertile Crescent: Fields and Rivers Essay

- Glaciers in Oregon Glaciers are a big part of life in Oregon. Glaciers supply drinking water, they irrigate crops and they help generate hydroelectric power. They are also a tourist attraction in areas that have more mountains. Glaciers are a natural resource that are so rare that people all over the world are trying to get these “frozen streams.” People want the power of glaciers because they can provide drinking water and people living in the city of La Paz, Bolivia rely on the melting of the glaciers....   [tags: Drinking Water, Irrigate Crops, Power]

Essay about How Does Climate Change Affects Glaciers

- Intro Glaciers have been around for millions of years and with the arrival of global warming there being threatened and challenged by warmer weather conditions and many of them have already melted and this has happened before but there has normally been a ice age and the glaciers just grow back but with the arrival of global warming the chance of a ice age has gotten much smaller and so has the chance of the glaciers that have melted to grow back or for new glaciers to form. For my global perspective I will be looking at the whitechuck glacier in Washington that from about 1970 to 2011 has retreated about 2 km and has lost half it's surface area....   [tags: weather conditions, warmer, melted]

Melting Glaciers are Devastating for Wetlands Essay example

- Melting Glaciers: Great News for Titanic, Devastating for Wetlands Overview This essay is dedicated to the importance of wetlands and the impending danger of rising sea levels due to global warming. Historically we humans have taken for granted the numerous vital roles played by wetlands in our ecosystem and viewed them only as unpleasant and undesirable. So we have destroyed much of our wetlands, and now that we finally see how important they are we are going to lose what little wetlands remain to rising sea levels....   [tags: Geology Global Warming]

Essay on Glaciers, Ice and Global Warming

- Glaciers, Ice and Global Warming Glaciers are one of the most fundamental phenomenon on the planet, and much of their purpose and impact on earth has been well documented and published. Ice sheets, Ice Caps and Glaciers trap nearly 90% of the world's fresh water, and are replenished by snowfall each year. Their existence on this planet dates back 650,000,000 years and yet they are always moving, always shifting and always melting. Before, human existence and even during the brief era of humans, ice dominated all of the earth's landmass and have regulated, created and altered many of the landscapes around the world....   [tags: Greenhouse Gases Climate Change Essys]

Writing About Glaciers in the Romantic Period Essay

- Glaciers, an integral feature of any mountainous landscape, were the focus of interest, curiosity and admiration for many travelers in the Romantic period, especially those in the Swiss region of Chamounix. During the 18th and 19th century, four of the voyagers who wrote excerpts on the glaciers were Coxe, Bourrit, Ramond and Shelley; these travelers made similar comparisons to each other regarding the nature of glaciers and the emotions evoked upon their viewing. In the late 18th and early 19th centuries, there was not a significant amount of scientific information known about the character of glaciers and therefore these travelers would not have had nearly the same exposure to factual inf...   [tags: Coxe, Bourrit, Ramond, Shelley]

Physics of Glacier Flow Essay

- How Glaciers Flow - Glaciers flow under the force of gravity as snow accumulates on the upper parts of the glacier and wants moves down slope. - The snow compresses to become ice and flows through the glacier into the ablation zone where it is lost. - If the accumulation equals the ablation than the glacier is said to be in equilibrium and its position will not change. This does not mean that the ice will not flow. Accumulation Zone The area where inputs occur into a glacier system. This usually occurs near the top of the glacier or ice sheet and such inputs to the system include snowfall, wind blown snow, rain and avalanches....   [tags: physics glaciers ice]
