The linked Flash animation illustrates the snowball earth hypothesis, that 900 million years ago, the entire terrestrial and oceanic earth surface was covered in ice. The animation demonstrates four proposed stages in snowball earth formation and destruction: normal, metastable, runaway snowball, and runaway greenhouse. This is part of a series of animations developed to help students visualize dynamic earth processes. The series is a component of a website that supports the textbook, Earth: Portrait of a Planet.
