Earth

From whence came the great sheets of ice that covered much of the earth during the ice ages? The ice was deposited rapidly, freezing mammoths in mid-chew on their tropical plant dinners. This astounding book describes the “canopy theory” of planetary development, that is, a spherical shell of mineral and water rotated at a distance from earth’s surface. Periodically minerals would fall, creating the stratification found in sedimentary rock and ice would fall, creating the geologically short-lived ice ages which disappeared as the ice melted.
