What Came First?
This earth history timeline activity relates events in the geologic past to distances measured on a piece of adding machine tape. Further activities are used to help the students visualize the sequence and spacing of the events. The site also contains numerous and varied links that will aid both the teacher and students in performing this activity. These links lead to detailed information on the stratigraphy, ancient life, and tectonics and allow visits to important type locations for each of the Precambrian, Paleozoic, Mesozoic, and Cenozoic ages.
