Question

Which factor best explains the difference in March sea ice between March in the northern hemisphere and March in the southern hemisphere? 
A)Low sun angle throughout the year 
B)High albedo for all surfaces 
C)Seasonal variation in daylength 
D)Continentality for all surfaces

Quizplus · Accepted Answer

The seasonal variation in daylength is the primary factor that explains the difference in March sea ice between the northern and southern hemispheres. In the northern hemisphere, March is the end of winter and the beginning of spring, while in the southern hemisphere, March is the end of summer and the beginning of autumn. This means that there is more solar radiation and longer days in the southern hemisphere, which causes more melting. In contrast, the shorter days and lower solar radiation in the northern hemisphere cause less melting and more sea ice to remain.
