question: What is the name for the energy waves that radiate out from the center of an earthquake?
distractor3: particle waves
distractor1: deep waves
distractor2: volcanic waves
correct_answer: seismic waves
support: Geologists study earthquake waves to “see” Earth's interior. Waves of energy radiate out from an earthquake’s focus. These waves are called seismic waves ( Figure below ). Seismic waves go different speeds through different materials. They change speed when they go from one type of material to another. This causes them to bend. Some seismic waves do not travel through liquids or gases. They just stop. Scientists use information from seismic waves to understand what makes up the Earth’s interior.
