What are facts about p-waves?

Answer 1

1. Waves of energy that travel through the Earth.

2. Result of an earthquake, explosion, or a volcano that imparts low-frequency acoustic energy.

3. Seismic waves are studied by geophysicists called seismologists.

4. Recorded by a seismometer, hydrophone (in water), or accelerometer.

5. Types of seismic waves: body wave, surface waves S waves and P waves.

6. Scientists have used indirect measurements and seismic waves from earthquakes to determine the internal structure of the Earth.

7. Scientists have seismographs set up all over the world to track movement of the Earth's crust.

8. Surface waves travel along the surface of the earth.

9. Typically the most destructive type during an earthquake.

10. Seismic waves are not always detectable by seismometers.

Answer 2

speed: 5.5 km/second (fastest)

arrival: first

damage: felt as a jolt, little damage

medium: travels through solids, liquids and gases

movement: push and pull

these are some basic facts on p-waves/primary waves

Answer 3

P-waves are the fastest type of seismic waves, traveling through the Earth's interior at a speed of about 5-8 km/s. They are compressional waves that move by pushing and pulling rock particles in the same direction as the wave's movement. P-waves can travel through solid and liquid materials, making them the first waves detected during an earthquake.

Answer 4

1. They are seismic waves

2. It compresses the ground and expands the area

3. P waves can move through solids and liquids
