Ch 22.4 Plate Tectonics

Author: deirdre carney
Description:
  • Explain the hypothesis of continental drift
  • Relate how the theory of plate tectonics explains sea-floor spreading, subduction, and formation of mountains
  • Explain the mechanisms of plate movement

Next Generation Science Standards

HS-ESS1-5. Evaluate evidence of the past and current movements of continental and oceanic crust and the theory of plate tectonics to explain the ages of crustal rocks.

HS-ESS2-1. Develop a model to illustrate how Earth’s internal and surface processes operate at different spatial and temporal scales to form continental and ocean-floor features.

Chapter 22.4 Plate Tectonics

Read Chapter 22.4 Plate Tectonics pg 676-683. Outline the reading in your Science Notebook & include major points and diagrams/tables.
You should focus on the following essential questions:
-What are plate tectonics and continental drift
-What are the roles sea-floor spreading and subduction in plate tectonics
-Why do tectonic plates move
-What are the types of plate boundaries and what are their characteristics
-Where do most mountains form
