Q: What type of waves radiate energy out from an earthquake's focus?


Read this paragraph and choose the correct option from the provided answers:

Geologists study earthquake waves to “see” Earth's interior. Waves of energy radiate out from an earthquake’s focus. These are called seismic waves ( Figure below ). Seismic waves change speed as they move through different materials. This causes them to bend. Some seismic waves do not travel through liquids or gases. Scientists use all of this information to understand what makes up the Earth’s interior.

 Choices:

- Microwaves

- abnormal

- volcanic

- seismic


A:
seismic
