Currently about what percent of earth's land surface is covered by glaciers (1 point)
a. 70%
b. 25%
c. 10%
d. 40%

If you look at the satelite map of the world, glaciers would appear white, yet most of the Earth's surface is green or brown - this suggests that it can't be too much. For example, in Africa only marginal parts (tops of mountains) are covered by glaciers.

The correct answer is 10% - mostly in Antarctica and Greenland.
