What is the difference between Love and Rayleigh waves?

• Love waves are more damaging than Rayleigh waves.

• Love waves travel in a horizontal direction, while Rayleigh waves move in an elliptical or rolling motion.

Which of the following apply to p-waves? (choose ALL that apply)

• compressional waves

• travel through solids, liquids, and gases

• only travel through solids

• fastest moving seismic waves

• shear waves

How have scientists been able to infer the internal structure of Earth without being able to directly observe inside the Earth?

• Scientists analyze how earthquake waves move throught Earth's interior.

• Scientists use satellite radar and sonar technologies to map Earth's internal layers.

• Scientists make educated guesses about Earth's internal structure based on previous hypothesis.

• Scientists study different types of rocks from many different locations on Earth's surface.
