Depositional Environments and Geologic History Labs part of Cutting Edge:Rates and Time:Teaching Activities
This is a pair of labs that incrementally prepare students to interpret the geologic history of a rock sequence. The first lab introduces students to depositional environments and fossils. The second lab presents a sequence of rocks from Bryce, Zion and the Grand Canyons. During the two labs, students learn first to interpret depositional environments from sedimentary rocks and then apply this to interpreting the changing environments through time in order to create a geologic history for this area of the American southwest.
