Question

What is accurate about seismic waves moving through the Earth? Group of answer choices P-waves (also called push-waves or sound waves) move through all liquids except Diet Pepsi, and s-waves (also called shear-waves) move through no liquids except Diet Pepsi. P-waves (also called push-waves or sound waves) move through solids, but s-waves (also called shear waves) don’t. S-waves (also called shear-waves) and p-waves (also called push-waves or sound waves) both move through both liquids and solids. P-waves (also called push-waves or sound waves) move through liquids, but s-waves (also called shear waves) don’t. Neither S-waves (also called shear-waves) nor p-waves (also called push-waves or sound waves) move through liquids.

Answer 1

Option (4)

Explanation:

Seismic P and S waves are generated during an earthquake that has the potential to propagate through the interior of the earth. P waves are also known as the primary waves and they move in a compression and extension way in their direction of propagation. S waves are shear waves. This P waves travel faster than the S waves and can travel in both solid as well as in liquid. Whereas the S wave can travel only through solids. They get absorbed when they reach the core-mantle boundary. These two waves are helpful in determining the epicenter of an earthquake by recording the arrival of these waves.

Hence, the correct answer is option (4).
