Which type of seismic wave is faster?

• P waves

• Love waves

• Surface waves

• S waves

How do P waves travel?

• In a circular motion

• In an up-and-down motion

• In a push-pull motion

• In a side-to-side motion

How many seismic stations are needed to accurately locate an earthquake's epicenter?

• Four

• Three

• Two

• One

What does the Richter scale measure?

• The damage caused by an earthquake

• The magnitude of an earthquake

• The depth of an earthquake

• The duration of an earthquake

What causes the P wave shadow zone?

• Absorption by the outer core

• Refraction due to different densities

• Reflection off the Earth's surface

• Interference with S waves
