Glacier
The permanent snow cover necessary for glacier formation is affected by factors such as the degree of slope on the land, amount of snowfall and the winds. Glaciers can be found in all latitudes except from 20deg to 27deg north and south of the equator where the presence of the descending limb of the Hadley circulation lowers precipitation so much that with high insolation snow lines reach above 6,500 m (21,330 ft). Between 19@N and 19@S, however, precipitation is higher and the mountains above 5,000 m (16,400 ft) usually have permanent snow.
