Question

What fraction of the earth did the former continental glaciers cover?

Answer 1

i think one third part of the earth

Answer 2

Answer:

About 30-35%

Explanation:

Glaciers are defined as the large moving blocks of ice that are formed by the gathering and solidification of snow on the high elevated mountains. The poles and near-polar region are suitable locations for the formation of glaciers as the high latitude areas experience a very cold type of climate.

During the last glaciation or ice age, the maximum portion of the earth that was occupied with glaciers was about 30-35% of the total landmass.  

At present, glaciers cover only 10% of the earth's total landmass that includes the glaciers, large ice caps, and the extensive sheets of ice that are present in Antarctica as well as Greenland.
