Step 1
Which sentence about P seismic waves is correct?
Answer
To identify the correct statement about P seismic waves, let’s evaluate each option:
-
P waves are slower than S waves: This statement is false. P waves (Primary waves) travel faster than S waves (Secondary waves).
-
P waves are transverse: This is incorrect. P waves are longitudinal waves, meaning they compress and expand the medium.
-
P waves can travel through solids and liquids: This statement is correct. P waves are the only type of seismic waves that can traverse both solid and liquid materials.
-
P waves can travel through solids but not liquids: This is false; as earlier stated, P waves can travel through both.
Based on this analysis, the correct answer is C.
