To retake a quiz, write the title of the quiz and your name and period at the top. As you answer each question, explain why you choose that answer. Turn in the quiz the next day to the basket by my computer.
Day 5 Quiz
1. According to the seismograph, which earthquake would have a higher magnitude?
a. B because it has a greater amplitude
b. A because it has a greater amplitude
c. B because it has a greater frequency
d. A because it has a greater frequency
2. If these waves were actually created by the same earthquake, which seismograph station must be closer to the epicenter?
a. B because the wave is shorter
b. B because the wave is taller
c. A because the wave is taller
3. What happens with the plates during an earthquake?

Day 6 Earthquake Quiz
1. The largest magnitude earthquakes occur on which type of boundary?
a. Divergent
b. Convergent
c. Transform
2. Two types of Siesmic waves accompany an earthquake. Which one create the most destruction?

b. No, they have no idea when earthquakes will happen
c. Yes, they can give warning months before the quake
d. No, they can only warn of a quake coming after the P waves are detected
Day 7 Volcanoes Quiz
1. How would you describe the viscosity of the magma coming out of a shield volcano like the ones from Hawaii?
a. The shield volcano spews out low viscosity magma.
b. The shield volcano spews out highly viscous magma.
