I read today that during low tilt (when seasonal variations are smaller) the summers are cooler and drier and winters are warmer and wetter, more snow is able to fall in the polar regions due to air's capacity to hold water vapor. And during cooler summers, less snow would melt. Thus, it is easier for glaciers to form.Perhaps the warm and wet winters allow for a moderate amount of snow and ice to accumulate, and the cool and dry summers keep it frozen for a longer period of time. Rain will often break up a layer of snow, and some snow might stay frozen at higher altitudes the entire winter given the summer is cool enough.On the Virgina regional test in the wiki...
The best conditions for snow and ice build-up over time (conditions leading to glaciations or iceages)
(warm/cold/wet/dry means ‘more than normal for that season’)
a) Warm summer and cold winters
b) Cool/dry summer and Warm/wet winters
c) Cold/wet winters and cool/wet summers
d) Dry/warm summers and wet/cold winters
I would think C, but the answer says B.. How is that?
So basically havenbro got it correct!
