The sky is pale blue in higher altitudes while it is deeper blue in lower altitudes. This is because there is more air molecule closer to earth surface (as a result of higher air pressure) than higher altitudes. The air molecules are responsible for scattering of sunlight hence giving the sky its blue hue. The more the air molecules the more the scattering.

The Milankovitch cycles in association with other natural factors explain how glaciers may advance and retreat over periods of d. ten thousand to one hundred thousand years.

According to this theory , these cycles together affect the amount of the solar heat that is incident towards the Earth's surface and the climatic pattern .
The Milankovitch cycle helps the advance and retreat of ice over the periods of 10,000 to 1000,000 years , but it does not explain the cause of Ice Age.
