Earthquakes release waves of energy that travel through rock, called?

Seismic Waves

200

Underwater earthquakes create large waves called

200

Which type of seismic wave is the fastest?

Primary or P waves

How does heat effect density?

Cooler materials are more dense and sink, Hotter materials are less dense and rise
