S waves and P waves are both types of seismic waves that are generated during an earthquake. These waves share some similarities, and here are the ones that apply:
1. They travel through solids: Both S waves and P waves can travel through the Earth's interior, but they have different properties. P waves, also known as primary waves, are compressional waves that can travel through solids, liquids, and gases. S waves, also known as secondary waves, are shear waves that can only travel through solids.
2. They shake the ground: Both S waves and P waves cause the ground to shake during an earthquake. However, they shake the ground in different ways. P waves cause the particles of the material they pass through to move in a back-and-forth motion parallel to the direction of the wave. S waves, on the other hand, cause particles to move in a side-to-side or up-and-down motion perpendicular to the direction of the wave.
To summarize, S waves and P waves are similar in that they both travel through solids and shake the ground during an earthquake. However, they have distinct characteristics and shake the ground in different ways.
