Today, glaciers exists on every continent on Earth except Australia. If we use the analogy that 1,000 ice crystals represent all of the glacier ice on Planet Earth, then we learn that:
Temperate glaciers exist on the continents of North America, South America, Europe, Africa, and Asia, on both islands of New Zealand, and on the island of Irian Jaya.
Today, there are glaciers in both the United States and Canada. In the US, glaciers exist in Alaska, Washington, Oregon, California, Montana, Wyoming, Colorado, and Nevada.
About 99.3% of Earth’s glacier ice is located in the polar ice sheets, with about 91.4% in Antarctica and about 7.9% in Greenland. Therefore, the remaining glacier ice, about 0.7% is located in “temperate” ice caps, ice fields, and glaciers.
Glacier ice is composed of hexagonal-shaped crystals composed of H2O molecules.
Yes and No – Theoretically speaking, the physical, chemical, thermal, and electrical properties of “refrigerator ice” and glacier ice are identical: viscosity, heat of fusion, latent heat, heat capacity, dielectric constant, thermal conductivity, absor
We do not know. The number may be as large as about 100,000. Currently, there are about 2,000 Alaskan valley glaciers. Of these, about a third (667) have been given official names by the U.S. Board on Geographic Names.
No – most of interior Alaska, south of the Alaska Range and north of the Chugach, Talkeetna, and Wrangell-St.
To date, the organic remains of Pleistocene mammals have not been found in a glacier.
No one knows for sure. In the Devils Hole, Nevada, paleoclimate record, the last four interglacials lasted over ~20,000 years with the warmest portion being a relatively stable period of 10,000 to 15,000 years duration.
