The following graphic shows the maximum and minimum areal extent of glaciation at each polar region. The maximum extent occurs during glacial periods. The minimum extent occurs during interglacial periods.
The areal extent of glaciation at the northern pole varies a great deal. The areal extent of glaciation at the southern pole does not vary much.
A few questions to ask yourselves...
Why does glaciation of the northern polar region vary so much?
Why does glaciation of the southern polar region vary so little?
What does the different extent of glaciation of each pole tell us about the planet's climate?
Glacial cycles are driven by northern hemisphere glaciation and deglaciation.
