Shadow Zone Presentation

P waves are compression waves that travel fastest, while S waves are shear waves that move slower and shake the ground side to side.

P waves are slower than S waves and move in a circular motion.

S waves travel fastest and are compression waves, while P waves are shear waves that move side to side.

Both P waves and S waves travel at the same speed and have the same motion.

Reflection occurs when waves bend at a boundary, while refraction occurs when waves bounce off a boundary.

Reflection occurs when waves bounce off a boundary, while refraction occurs when waves bend as they pass through materials of different densities.

Reflection and refraction both occur only at the Earth's surface.

Refraction only happens in the atmosphere, not in the Earth's crust.

Density of the material

Temperature of the material

Presence of water

P waves are compression waves that travel fastest, while S waves are shear waves that move slower and shake the ground side to side.

P waves are slower than S waves and move side to side.

S waves are compression waves that travel fastest, while P waves are shear waves that move slower.

Both P waves and S waves move at the same speed and in the same way.
