Rock Layers and Fossil Analysis

Miss Higgins recaps the previous lesson on rock layers at Desert Rocks National Park, explaining how the lower layer formed in a floodplain and the upper layer in a deep ocean. The lesson continues with an analysis of how rock layers form over time through sedimentation, using diagrams and illustrations. Students are then tasked with applying this knowledge to Constantan Cliff in England. The video concludes with instructions for an assignment on Google Classroom, where students will analyze a text and present their findings.
