- نبذة مختصرة :
Several periods of earth history were marked by major glacial episodes. Possible causes of these episodes include the movement of Earth's continental areas into higher latitudes, changes in atmospheric composition and motion, and changes in Earth's orbit. Effects of the ice ages included substantial changes in sea level and coastal topography, alteration of lake and river drainage, and the shifting of plants and animals accompanying the changing climates.
