What orbital configuration favors glaciation? Why?

What will be an ideal response?


The best orbital configuration for a glaciation would be to have mild summers that do not lead to significant melt-off from the winter snow. This way, the glaciers can continue to accumulate snow and ice, growing annually in size. Northern hemisphere glaciation is favored when eccentricity is large, the precessional state is such that summer occurs at aphelion, and obliquity is at a minimum.
