Let’s Review: 1. What is continental and plate tectonics theory all about? 2. How are these theories related to the formation of plate boundaries? 3. What are the different types of plate boundaries? 4. What are the geologic features formed from each boundary? Learning Objectives: I can… • Identify the different tectonic forces • Explain the effect of the movement plates that leads to the formation of folds and faults • Relate the current phenomena (e.g. Coral Garden in Loon Bohol, etc.) to how movement of plates leads to the formation of folds and faults Let’s see these geologic features… Guided DIY Activities 1. 2. 3. 4. 5. 6. Form 6 groups with 6-7 members each Perform one of the two activities based from the materials assigned to you Activity 1: Fold the Clay (Gr. 1-3) Activity 2: The Faulty Set-up (Gr. 4-6) Follow the procedures from the given worksheets Answer the guide questions after performing the activity Prepare for a short presentation/simulation afterwards Have fun!! Materials Needed: • 4 blocks of modeling clay in different colors • Old newspapers Materials Needed: • Mayonnaise • 3 pairs of Graham crackers • 3 pairs of sliced bread • Plastic gloves • Platter Sample Worksheets Tectonic Forces and Processes • Deformation refers to the change in the original shape and size of a rock. • When rocks are subjected to stresses (tectonic features), they begin to deform. Deformation Folding Faulting Tectonic Forces and Processes Folding • This occurs when rocks are pushed towards each other from the opposite sides. Tectonic Forces and Processes Anticline- upward arch Syncline – downward arch Limbs- sides of the folds Dome – a circular or elliptical anticline in which limbs dip away in all directions. Tectonic Forces and Processes Tectonic Forces and Processes Faulting • It is the fracturing and displacement of brittle rocks strata along a fault plane. Normal Fault Reverse Fault Strike-Slip Fault Tectonic Forces and Processes Practice Exercise Guide Questions: 1. What are the significant effects of the movement of plates to the formation of these geologic activity/ features presented from the article? 2. How do these effects affect the community and society? Assignment Write an essay summarizing the “big ideas” you have learned from the articles on how movement of plates leads to the formation of folds and faults in a 1 whole sheet of paper.
