Earth’s Crust and Resources Assessment
Science 7
1. Describe the impact on the environment and on society of past and current
catastrophic geological events. Describe the scientific understandings we have of the
movements and forces within the earth’s crust. Include diagrams with your written
answer.
Hint: Include topics such as:
 plate tectonics,
 volcanic activity
