Rocks within Earth both expand and contract as P waves pass
Explanation:
Rocks within the earth both expands and contracts as P-waves passes through them. P-waves are elastic waves.
- Elastic waves behaves in such a way that they do not cause permanent deformation of rocks.
- They can be said to cause elastic deformation when they travel through rocks.
- They simply temporarily expand and contract the rock within a short period by causing the vibration of particles of the medium.
- After a short while, the rock returns back to its original position as if nothing has happened to it.
- These elastic waves are better called seismic waves.
- P-waves are primary waves that can travel through any medium.
