TEKS 8.9A – Plate Tectonic History
TEKS 8.9B – Plate Tectonic Theory
Answer the questions below on the back and use this as your study guide for the test.
To be successful on this standard, I must know:
1. What is the Continental Drift Theory, evidence for it, and which scientist is responsible for it?
2. What is the Sea Floor Spreading Theory, evidence for it, and which scientist is responsible for it?
3. What is the Convection Current Theory, evidence for it, and which scientist is responsible for it?
4. What is the Plate Tectonic Theory, evidence for it, and which scientist is responsible for it?
5. Which layer of the Earth does convection occur in and what is it made of?
6. Which layer of the Earth is divided into tectonic plates and what does it move along?
7. What are the 3 types of plate boundaries and draw arrows depicting their direction of motion?
8. What landforms are created on land and in the ocean at a divergent boundary?
9. What landforms are created on land and in the ocean at a transform boundary?
10. What are the 3 different types of convergent boundaries?
11. What landforms are created on land at a continent/continent convergent boundary?
12. What landforms are created on land and in the ocean at a continent/ocean convergent
boundary?
13. What landforms are created on land and in the ocean at an ocean/ocean convergent boundary?
14. What is subduction and what happens to the plate that sinks as it moves further into the
asthenosphere?
