P (primary) waves and S (secondary) waves provide substantial data about the earth’s interior. Write down two major differences between the two different waves.
Answers
Answer:
Explanation:
Type of Wave
Primary waves are made up of compression waves, also known as push-pull waves. The individual
Wave Sizes
S waves are generally larger than P waves, causing much of the damage in an earthquake. Since the particles in an S wave move up and down, they move the earth around them with greater force, shaking the surface of the Earth. P waves, though easier to record, are significantly smaller and do not cause as much damage because they compress particles in only one direction.
l waves, therefore, push against one another, causing a constant parallel, straight motion. S waves are transverse waves, which means they vibrate up and down, perpendicular to the motion of the wave as they travel. In an S wave, particles travel up and down and the wave moves forward, like the image of a sine wave.
