Comment on this resource
Earth has been significantly altered over its 4.6 billion year history by climate swings, volcanism, and drifting continents. These dynamic conditions, in turn, have influenced every living thing that has inhabited the planet. This interactive timeline discusses the concept of deep time, and allows users to learn about geological events, evolutionary transformations, and the extinction of species or whole families of organisms that once inhabited the planet, and to better appreciate the vast period of time over which these transformations have occurred. A background essay and discussion questions are included.
