Question

Ho does this sound? does it make sense?

Answer 1

1. What did you observe happened when a P-wave traveled from a solid to a liquid?

It depends what the incident is, but because Primary waves don’t travel through liquid, a portion of the energy is converted to a Secondary Wave, and then a portion of it is also reflected, but the energy mainly disappears because it absorbs into the liquid.

2. What did you observe happened when an S-wave traveled into a liquid?

It spread the particles making them faster through the liquid faster than it would by air.

3. In your own words, describe how a primary wave moves.

Primary waves travel super fast through solids, such as rock, that causing particles in the rock to vibrate in the same direction as the waves are moving which causes an earthquake.

4. In your own words, describe how a secondary wave moves.

Secondary waves move through solids, such as rock like materials, causing particles in the rock to vibrate at right angles to the direction the waves are moving, also causing an earthquake.

5. How do earthquakes help us learn about the interior of the Earth?

By Primary waves. Primary waves can travel through anything such as solid rock, magma, water, and gas. S-waves can only travel through solids. That shows that if only a Primary wave made it to the seismic station or the interior of earth, the Secondary wave was stopped by the liquid outer core.
