P waves can travel through liquid and solids and gases, while S waves only travel through solids. Scientists use this information to help them determine the structure of Earth.
S waves have a larger amplitude than P waves and cause the ground's surface to move both vertically and horizontally, making them more dangerous. Surface waves, which move slowly, are the last to arrive. P waves leave the earthquake first and go the furthest. Rock oscillates perpendicular to the direction of wave propagation in S or shear waves. In rock, S waves typically move at a pace of roughly 60% that of P waves, and they always come after the latter. Points of solid media move back and forth perpendicular to the wave's direction of propagation due to S waves, also known as shear or transverse waves. As the wave passes, the medium is sheared first in one direction and then in the opposite direction.

Hi. "Tidal wave" suggests a wave associated with the ebbs and flows related to the relative positions of the earth, moon and sun. These rises and falls relative to mean sea level are periodic and easily predictable. But the enormous wave generated by an earthquake is probably even less easy to predict than an earthquake and of no regular (that is, periodic) recurrence that anyone knows of. But I think "tsunami" is not too bad a name for such earthquake-generated waves as tsunami does not suggest any strong link with the relative positions of the earth, moon and sun.
Answer:
Because, a natural hazard is a threat of a naturally occurring event will have a negative effect on humans.
Explanation:
Answer:
3. we would not exist because we are made of material that was recycled in galaxies.
Explanation:
If stars are randomly distributed in space, the elements like Hydrogen, Nitrogen, etc that releases when stars are dieing will not be close enough to come together to form a planet and thus lead to the formation of life on Earth.
