Video Learning Notes

This lesson explored how evidence from the ages of continental and oceanic crust supports the theory of plate tectonics. Students analyzed data showing oceanic crust ages increase with distance from mid-ocean ridges due to seafloor spreading, and how continental crust ages reflect past plate interactions. Radiometric dating was highlighted as a key method for determining crustal rock ages. Through evaluating and revising explanations based on evidence, students practiced scientific reasoning and deepened their understanding of Earth's dynamic crust.

Learning Goals

• Analyze evidence of past and current movements of continental and oceanic crust.
• Explain how the theory of plate tectonics accounts for the ages of crustal rocks.
• Interpret data showing how oceanic crust ages increase with distance from mid-ocean ridges.
• Describe how continental crust ages vary relative to ancient continental cores due to past plate interactions.
• Use scientific reasoning to evaluate and revise explanations about crustal rock ages based on evidence.
