* glacier = accumulated and compacted ice | |||
* glaciers accumulate when winter snowfall does not melt during the other seasons | |||
** because they accumulate from precipitation (snowfall), glaciers are made of "fresh" or non-salt water | |||
* glaciers hold about 2.1% of the earth's water | |||
* 10% of the earth is covered by glacial ice | |||
* 69% of the earth's fresh water is held in glaciers | |||
