Answer:
If an earthquake occurs nearby, it would be the P waves to reach the Earth's surface first.
Step-by-step explanation:
- The compressional waves formed during an earthquake are known as P waves.
- These waves are faster than the shear waves (popularly known as S waves) and thus reach the Earth's surface before the shear waves do.
- Sizewise, the P waves are smaller than the S waves and comparatively cause less damage.
- The difference between the time of these waves reaching the Earth's surface allows seismologists to fetch crucial information about the earthquake.
