Discuss the causes of large-scale glaciation and the controls on ice advances and retreats within ice ages. What will be an ideal response?
Glacial events in Earth history are primarily controlled by plate tectonics, which affects such
factors as the position of continents, the location of mountain belts (which impact
precipitation patterns), continental size, and the position of oceanic and atmospheric
circulation patterns. Fluctuations within ice ages are probably controlled by Milankovitch
factors, which are related to the amount of solar heat reaching Earth.
