Warm-up  1. What does the Richter scale measure?  2. What is the difference in the amount of energy released as you go up one number in the Richter scale (from a 4.0 to a 5.0, for example)?  3. What does the Mercalli scale measure?  4. What are some things that might affect the amount of damage?  5. Which scale is more accurate? Why?

Warm-up  1. Which earthquake waves: a. Travel the fastest? b. Travel the slowest? c. Can move through solids only? d. Can move through liquids and solids? e. Can create massive destruction when close to the center of the earthquake?  2. What are shadow zones? How do these provide evidence for the presence of an outer liquid core inside the Earth?
