I want to know the answer to the following question:
Between which latitudes to mountains tend to have permanent snow?
All the background I'm provided with is that "Glaciers can be found in all latitudes except from 20° to 27° 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).". Is that enough to answer the question?
