How are P waves different from S waves?(1 point) Responses P waves cause damage, and S waves do not cause damage. P waves cause damage, and S waves do not cause damage. P waves travel slowly, and S waves travel quickly. P waves travel slowly, and S waves travel quickly. P waves push and pull in the same direction as the wave, and S waves move up and down. P waves push and pull in the same direction as the wave, and S waves move up and down. P waves move under Earth’s surface, and S waves move along Earth’s surface.
P waves push and pull in the same direction as the wave, while S waves move up and down.
P waves push and pull in the same direction as the wave, while S waves move up and down.
P waves and S waves are different types of seismic waves that are generated during an earthquake.
To understand their differences, we need to consider their properties and behavior.
P waves, also known as primary or compressional waves, are the fastest seismic waves and are the first to be detected during an earthquake. They travel by compressing and expanding the rocks in the same direction as the wave propagates. Think of it like squeezing and stretching a slinky toy in a back and forth motion along its length. P waves can travel through both solids and liquids, as they can compress and expand the material they pass through.
S waves, also known as secondary or shear waves, are slower than P waves and are the second type of waves to be detected. They travel by moving the rocks perpendicular to the direction of wave propagation, like shaking a rope side-to-side. S waves can only travel through solids because they require the ability of the rock particles to shear or move past each other. They cannot pass through liquids or gases.
Now, let's address each option in the question:
1. "P waves cause damage, and S waves do not cause damage." - Both P waves and S waves can cause damage during an earthquake, but the type and severity of the damage may vary in different situations. Generally, P waves are less destructive compared to S waves, but there are exceptions.
2. "P waves travel slowly, and S waves travel quickly." - This statement is incorrect. P waves are faster than S waves.
3. "P waves push and pull in the same direction as the wave, and S waves move up and down." - This statements correctly describes the direction of motion for P and S waves. P waves push and pull in the same direction as the wave, while S waves move up and down or side-to-side.
4. "P waves move under Earth’s surface, and S waves move along Earth’s surface." - This statement is incorrect. P waves can travel through both the Earth's interior and its surface, while S waves only travel along the Earth's surface.
