Geological time periods

Geologists have organized the history of the Earth into a timescale on which large chunks of time are called periods and smaller ones called epochs. Each period is separated by a major geological or paleontological event, such as the mass extinction of the dinosaurs which occurred at the boundary between the Cretaceous period Click “Deep Time” to see the timeline: http://www.pbs.org/wgbh/evolution/change/deeptime/index.html

Roll your mouse over the different shapes on the timeline under the three main ideas, Geology, Transformation and Extinction to view the main ideas, You may use this resource but IF you get REALLY stuck, click on the pictures and they will take you to another site,… but NOT recommended. (Deep Time is easier!)
