Question

Quizplus · Accepted Answer

P waves, also known as primary waves, are longitudinal waves that move through solid and liquid materials, including the earth's interior. They move in a push-pull, expanding and compressing motion, similar to sound waves. P waves can travel through the earth's core, but they are slightly refracted as they pass through the outer core, causing them to change direction slightly.
