four facts about glaciers

By

—Credit: Ted Scambos, NSIDC. The balance between the advance and ablation of glaciers, termed as mass balance (or budget), is an essential measure in sustaining Earth’s ecosystem. Most of the earth is covered with water, and most of that is salty and in the oceans. Glaciers are found on about 10 percent of Earth's land area, with most of them found in the Arctic and Antarctica regions, but some occurring high up on mountains, even in tropical areas. These glaciers develop in high mountainous regions, often flowing out of icefields that span several peaks or even a mountain range. On 1916 the Grand Pacific Glacier was at the head of Tarr Inlet about 65 miles (105 km) from Glacier Bay’s mouth. 9. Learn some interesting facts about glaciers, like how much of the planet they cover and where they can be found. Mountain glaciers. Alaska’s Muir Glacier, like many Alaskan glaciers, has retreated and thinned dramatically since the 19th century. Approximately 10 percent of the Earth is covered by glaciers; during the last Ice Age, they covered one-third of the Earth’s surface. Easily accessible, it is the most visited glacier in North America. Interesting Ice Age Facts: 36-40. Snow is compacted and turns to ice. Crevasses rumple the surface of Crane Glacier in Antarctica. In fact, about 97% of Earth's water is ocean water. Glaciers develop over many years in places where snow has fallen but not melted. Read "Interesting Facts About Glaciers - Geology for Beginners | Children's Geology Books" by Baby Professor available from Rakuten Kobo. Glaciers play a significant role as reservoirs of water, habitats for species, enhancing electric power generation, as well as serving as tourist destinations. This is the fastest documented glacier retreat. Glaciers are dynamic, and several elements contribute to glacier formation and growth. Glaciers - just what exactly are they? There are seven tidewater glaciers in the park: Margerie Glacier,McBride Glacier, Grand Pacific Glacier, Lamplugh Glacier, Johns Hopkins Glacier, Gilman Glacier, and LaPerouse Glacier. Together with CO 2, this released methane leads to greenhouse effect, which is causing global warming and hence, rapid melting of polar ice and glaciers, which is turn is actually stalling glaciation (remember that we are in interglacial phase). Glacier ice is the largest reservoir of fresh water on the planet, storing an estimated 75 percent of the world’s supply. Glaciers exist in both the United States and Canada. The Athabasca Glacier is one of the six principal 'toes' of the Columbia Icefield, located in the Canadian Rockies.The glacier currently loses depth at a rate of about 5 metres (16 ft) per year and has receded more than 1.5 km (0.93 mi) and lost over half of its volume in the past 125 years. Here are 10 interesting facts about glaciers: 10. 5 Unusual Facts About Glaciers. 36. This particular pair of images shows the glacier’s continued retreat and thinning in the second half of the 20th century. Most U.S. glaciers are in Alaska; others can be found in Washington, Oregon, California, Montana, Wyoming, Colorado, and Nevada (Wheeler Peak Glacier in Great Basin National Park).Reputedly, Utah’s Timpanogos Glacier is now a rock glacier (in which the ice is hidden by rocks), and Idaho’s Otto Glacier has melted away.Canada Snow falls in the accumulation area, usually the part of the glacier with the highest elevation, adding to the glacier's mass.As the snow slowly accumulates and turns to ice, and the glacier increases in weight, … 8.
