What happens to particles when p waves and s waves pass through them?
a. p waves twist particles as they pass through materials. s waves cause particles to compress as they pass through materials.

b. particles are squeezed together and pushed apart by p waves. particles slide past each other in a crosswise direction as s waves pass through them.

c. particles travel in waves as p waves pass through materials. particles twist and shake as s waves pass through materials.

d. p waves cause an increase in pressure on particles of materials as they pass through. s waves decrease pressure on the particles of materials as they pass through.

B. Particles are squeezed together and pushed apart by P waves. Particles slide past each other in a crosswise direction as S waves pass through them.

Explanation:

P waves and S waves are body waves that are part of the seismic waves, which comprises all types of energy that travel through earth´s layers, in the form of waves, this waves can be generated by earthquakes, volcanic activity, landslides and even human activities like detonations or perforations.

P waves are PRIMARY WAVES, which are compression waves that travel through solids and fluids in the same direction as the wave itself. Similar to sound, each particle is pushed and pulled by the particle directly behind, this results in a very high propagation speed that makes this, the first waves to arrive at a seismograph station in an earthquake

S waves are SECONDARY WAVES, which are shear waves that move the ground in a perpendicular direction to the propagation of the wave, this waves can´t travel through liquids. particles slide in a shear plane relative to the particles behind, like a wave moving through a tensioned string, generating an up and down movement as it moves on.

away from the curb

explanation:

the wheels would then hit the curb if it started to rolling, decreasing the chance of an accident.

qualitative observation deals with data that can be observed with our senses: sight, smell, touch, taste, and hearing. they do not involve measurements or numbers. for instance, colors, shapes, and textures of objects are all qualitative observations.
