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.
