Question

In earthquakes, P waves:

Group of answer choices

Travel towards the focus

Are faster than S waves

Are absent

Arrive more slowly than surface waves

Answer 1

Are faster than S waves

Step-by-step explanation:

In earthquakes, P waves, or primary waves, are the fastest-moving type of seismic wave. They are compressional waves, meaning that they move through the ground by pushing and pulling the rock in the direction that the wave is moving. Because they are the fastest-moving type of seismic wave, P waves are typically the first to arrive at a seismograph station, followed by S waves (secondary waves) and then surface waves. P waves can travel through solid rock, liquid, and gases, making them a useful tool for studying the interior of the Earth.
