The flat rings of outside the nebula became the orbit paths, and that is where the planets stay and rotate around the sun. After that dust particles and gases that were found were all combined up to create planets and moons.
P-waves
Explanation:
P-waves are compressive longitudinal waves that are capable of passing through the liquid outer core.
- P-waves are also called primary waves.
- They are seismic waves that can pass through any medium
- They usually arrive at a seismic station first before the s-waves.
- P-waves have the highest velocity of all seismic waves.
- Together with the s-waves they are called body waves.
- P-waves moves parallel to the source and forms series of rarefactions and compressions
