Answer

Brief Explanations:

The leading scientific theory for ice ages is the Milankovitch cycles, which describe how variations in Earth's axial tilt, orbital shape (eccentricity), and precession change the amount and distribution of solar radiation reaching Earth's surface, driving glacial and interglacial periods. The other options are either evidence of past climate changes (tree rings, pollen) or not the primary drivers of ice ages.

Answer:

the tilt of the Earth's axis and the shape of its orbit
