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. Form 6 groups with 6-7 members each
2. Perform one of the two activities
Materials Needed:
• 4 blocks of modeling clay in different colors based from the materials
• Old newspapers assigned to you
Activity 1: Fold the Clay (Gr. 1-3)
Activity 2: The Faulty Set-up (Gr.
4-6)
3. Follow the procedures from the given worksheets
4. Answer the guide questions after performing the activity
5. Prepare for a short presentation/simulation afterwards
6. Have fun!! 
Materials Needed:
• Mayonnaise
• 3 pairs of Graham crackers
• 3 pairs of sliced bread
• Plastic gloves
• Platter

Sample Worksheets

Tectonic Forces and Processes
Deformation
• 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.
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

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.
