Geologic History - Unit 7
Please be patient as we transition from MyBigCampus - some of the video links may not be active at the moment, but will be up and running soon!
Earth has been significantly altered over its 4.6-billion-year history by climate swings, vulcanism, drifting continents, and more. These dynamic conditions, in turn, have influenced every living thing that has inhabited the planet. This interactive timeline from the Evolution Web site provides a framework through which to learn about geological events that have shaped the planet and its past and present life forms, and to better appreciate the timescale over which numerous remarkable transformations have occurred.
