Question

1. since p - waves bend and change speed as they travel through earth, what does this tell us about the materials inside our planet?

Explanation:

P - waves are compressional waves. Their bending (refraction) and speed - changes occur due to variations in the density and elasticity of materials. Different materials inside the Earth cause these changes, indicating that the Earth's interior is composed of materials with varying physical properties such as density and composition.

Answer:

The materials inside the Earth vary in density and other physical properties.
