• Seismic waves
• Gravity waves
• Chemical energy

The focus of an earthquake is

• The point (below Earth's surface) where rocks first begin to break and the first movement occurs
• The closest seismic station
• The place where the greatest damage occurs
• A fault

P and S waves travel through the earth, and so are called

• surface waves
• body waves
• tsunamis
• earth waves

What does P in a P wave stand for?

• peridot
• picky
• primary
• partial

What does S in an S wave stand for?

• super
• secondary
• slow
• sideways

Which travels fastest, always being the first detected by seismic stations?

• P waves
• S waves
