Why is glacier water so blue?
A large piece of compressed ice, or a glacier, similarly appears blue. … Rather, water ice is blue for the same reason that large quantities of liquid water are blue: it is a result of an overtone of an oxygen–hydrogen (O−H) bond stretch in water, which absorbs light at the red end of the visible spectrum.
Is glacier ice safe to drink?
Think that ice-blue water pouring out of a beautiful mountain glacier is safe to drink untreated? Think again. … The research suggests fecal bacteria can survive inside glaciers for much longer than previously thought, flowing downhill with the ice, and potentially infecting water sources tens of miles away.
What is the oldest glacier?
How old is glacier ice?
- The age of the oldest glacier ice in Antarctica may approach 1,000,000 years old.
- The age of the oldest glacier ice in Greenland is more than 100,000 years old.

What is the largest glacier in the United States?
The largest glacier in the United States is the Bering Glacier, near Cordova, Alaska.
How do glaciers help keep us cool?
As the planet’s air conditioner, the polar ice caps impact weather and climate dynamics, such as the jet stream. … For example, glaciers’ white surfaces reflect the sun’s rays, helping to keep our current climate mild. When glaciers melt, darker exposed surfaces absorb and release heat, raising temperatures.
What does Ice Age mean in geography?
Ice age, also called glacial age, any geologic period during which thick ice sheets cover vast areas of land. Such periods of large-scale glaciation may last several million years and drastically reshape surface features of entire continents. A number of major ice ages have occurred throughout Earth history.
How far is Anchorage from Matanuska Glacier?
