Glacier Quick Facts - National Snow and Ice Data Center
What are ice caps and icefields? An ice cap is a type of glacier, covering less than 50,000 square kilometers (20,000 square miles). Like ice sheets, ice caps tend to spread out in dome-like shapes as opposed to flowing down slopes.
What is the Cryosphere? | National Snow and Ice Data Center
The cryosphere refers to Earth’s ice in all its forms. The term comes from the Greek word for icy cold—krios. The cryosphere includes: This up-close image shows the intricate details within this ice block in Canal Park, Duluth, Minnesota. — Credit: clairity/Flickr A few basic facts about ice ...
