The Geologic History of Illinois
Join Dr. Dennis Kolata of the Illinois Geologic Survey as he takes us on a "Geologic Trip through Illinois." Dr. Kolata discusses how the seas moved in and out of Illinois many times over the past billion years and in the process eroded land surfaces for some of the time and deposited new rock at other times. Explore some of the plant and animal fossils found in Illinois and see how many of the minerals and rocks of this area were once formed. This is a must for every earth science classroom in Illinois!
