Is the eccentricity of a circle 0 or 1? I have seen conflicting answers..

...I'm not sure how that's exactly related to Meteorology, but the eccentricity of a circle is 0. The more elliptical it gets (i.e. longer and skinnier), the higher the eccentricity gets until it becomes a parabola, which has an eccentricity of 1.

Eccentricity is part of the Milankovitch Cycle, which we have to know.

Oh wow, all these tests say that the eccentricity of a perfect circle is one...

Come on test makers!!!

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)
are:
(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?

Warm winters are good for ice buildup??????? I totally agree with you tornado guy, I would have picked C too.

I really don't get this solution... I would have also picked C.

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.

That makes sense.
