1. Plate Tectonics Lab February 2015

2. Types of Plate Boundaries ConvergentDivergentTransformSubduction

3. Convergent Where two plates are colliding Where two plates are colliding Example: Himalayas between Eurasian Plate and Indian Plate Example: Himalayas between Eurasian Plate and Indian Plate

4. Divergent Where two plates are moving away from each other Where two plates are moving away from each other Example: East African Rift Example: East African Rift

5. Transform Where two plates are sliding past each other Where two plates are sliding past each other Example: San Andreas Fault along the west coast of California Example: San Andreas Fault along the west coast of California

6. Subduction A type of convergent boundaries where one plate is moving under another one A type of convergent boundaries where one plate is moving under another one Example: The Andes in South America where the Nazca Plate is moving under the South American Plate Example: The Andes in South America where the Nazca Plate is moving under the South American Plate

7. Activity Gather supplies Gather supplies Wax paper Wax paper Graham crackers – Continental plates Graham crackers – Continental plates Fruit roll up pieces – ocean plates Fruit roll up pieces – ocean plates Frosting - asthenosphere Frosting - asthenosphere Using the supplies make examples of each of the 4 types of plate boundaries Using the supplies make examples of each of the 4 types of plate boundaries Draw each situation in your notebook Draw each situation in your notebook

8. Activity continued For divergent: start with the two pieces of crackers close together then move them apart For divergent: start with the two pieces of crackers close together then move them apart For transform: start with the two pieces of crackers close together and slide one up and one down For transform: start with the two pieces of crackers close together and slide one up and one down For subduction: use the fruit roll up piece and slide it under one of the crackers For subduction: use the fruit roll up piece and slide it under one of the crackers For convergent: wet the side of one of the crackers, slide the wet side into the side of another cracker For convergent: wet the side of one of the crackers, slide the wet side into the side of another cracker

9. Activity Quesions 1. Explain the strong points of how this model is a good model for understanding tectonic plate movement. 2. Explain the weak points of how this model is a poor example for understanding tectonic plate movement.
