Movement of Plates

Causes of Plate Movements

by Jomar Dolindo

​Most Essential Learning Competency

​Describe the possible causes of plate movements.

​Learning Objectives

1. ​Describe and simulate seafloor spreading.

2. ​Illustrate the convection current within the mantle that could possibly affect plate movement.

3. ​Discuss how ridge push and slab pull cause plate movement.

4. ​Explain the causes of plate movement based on Continental Drift Theory and Seafloor Spreading Theory.

5. ​Be aware of the effects of different processes and forces in our environment.
