15 Questions
Which type of body wave is known for its compressional or longitudinal motion?
Primary waves
What property of P waves allows them to pass through any type of material?
They do not weaken as they travel
Why do seismologists detect only P waves in certain layers of Earth's interior?
Because the layer is liquid
