Question

multiple-choice question

1. what type of waves travel through materials?

a. surface waves
d. water waves
b. seismic waves
c. body waves

Explanation:

To determine the correct answer, we analyze each option:

• Option a (Surface waves): These waves travel along the surface of a material (like the surface of the Earth or water), not through the material's interior.
• Option d (Water waves): These are a type of surface wave in water and also travel along the surface, not through the water's bulk material in the way we're considering here.
• Option b (Seismic waves): Seismic waves include both body waves (which travel through the Earth's interior) and surface waves (which travel along the surface). The term "seismic waves" is a broader category, and the question is about waves that travel through materials (the interior).
• Option c (Body waves): By definition, body waves are seismic waves that travel through the interior of a material (like the Earth's crust, mantle, etc.). They move through the bulk of the material, as opposed to surface waves which stay near the surface.

Answer:

c. Body waves
