how are p waves diffrent from s waves
A:p waves move earths surface and s waves move along earths surface
B:p waves push and pull in the same direction as the wave, and s waves move up and down
C:p waves travel slowly, s waves travel quickly
D:p waves cause damage, s waves do not
The correct answer is B: P waves push and pull in the same direction as the wave, while S waves move up and down.
P waves, also known as primary waves, are the fastest seismic waves and have a compressional motion. They push and pull the particles of the rock in the same direction as the wave is traveling.
S waves, also known as secondary or shear waves, are slower than P waves and have a transverse motion. They move the particles of the rock perpendicular to the direction of wave propagation, causing them to oscillate up and down or side to side.
The options C and D are incorrect because they do not accurately represent the differences between P waves and S waves. Option A is incorrect because both P and S waves can cause movement of the Earth's surface in different ways.
