20.2.1. Plate Tectonics Theory

Try these first

1. 1.

   What are the three types of plate boundaries?

   Hint

   Think of how they interact with each other.

2. 2.

   What is the main cause of earthquakes at plate boundaries?

   Hint

   Recall the roles of stress.

3. 3.

   What type of plate boundary is characterized by plates moving apart?

   • Convergent
   • Divergent
   • Transform

   Hint

   Remember locations like the Mid-Atlantic Ridge.

4. 4.

   True or False: The San Andreas Fault is a convergent boundary.

   • True
   • False

   Hint

   Recall what happens at transform boundaries.

5. 5.

   Discuss how plate tectonics can explain the distribution of earthquakes globally. Provide examples for each type of boundary.

   Hint

   Relate examples to specific tectonic settings.

6. 6.

   Critically analyze an earthquake’s risk assessment in urban planning near a fault line. How should this influence structural designs?

   Hint
