Finally Friday!

We discussed our findings on earthquake waves:

• P-waves (Primary waves) are the fastest and first to travel during a quake
• S-waves (Secondary waves) come after the p-waves
• Surface waves arrive last and cause the most destruction

**BONUS** Can you tell me what name(s) seismologists call surface waves? If so, bring your answer into class on Tuesday!

Be sure to study your Lesson 10 and 11 notes  for a quiz on Friday, October 2.

Hope you enjoy the 3-day weekend!
