P-wave

The video tutorial explains the nature of P waves, which are compression waves similar to sound waves in air. It contrasts P waves with S waves, highlighting that P waves travel faster and are recorded by seismometers before S waves. The P in P waves stands for primary, indicating their speed advantage over S waves, where the ground vibrates perpendicular to the wave direction.

What type of wave is a P wave similar to?

• Sound wave

• Light wave

• Radio wave

• Water wave

How does the ground vibrate in relation to the direction of S waves?

• In a random pattern

• In a circular motion

• Perpendicular to the wave direction

• Parallel to the wave direction

What does the 'P' in P wave stand for?

• Pressure

• Primary

• Parallel

• Perpendicular

Which type of wave is recorded first by a seismometer?

• Rayleigh wave

• Surface wave

• P wave

• S wave

Why are P waves faster than S waves?

• They are compression waves

• They travel through liquids only

• They have a higher frequency

• They are surface waves
