Ice Age



A few questions: I am trying to evaluate a posting elsewhere re the causes
of a glaciation: Pick a question or two and enjoy:

1) What is the precession period of the Earth's spin axis?

2) What is the "Precession of the Equinoxes"? Is there is difference from
the above?

3) What would cause a periodic change in the eccentricity of the Earth's
elliptical orbit?

4) Please review why the orbit precesses: GR is needed here as I
recall. I assume that the orbits of all the planets precess as well as
that of Mercury.

5) Who is Milutin Milankovich?
