Question

select the correct answer. why do sound waves move faster through the ground than through the air? a. particles of matter are packed more loosely in the ground than in the air. b. particles of matter are packed more tightly in the ground than in the air. c. air doesnt contain any particles of matter to transmit sound waves. d. the elevation of the ground is lower than the elevation of the air space.

Explanation:

Sound waves are mechanical waves that require a medium to travel. The speed of sound depends on the density of the medium. Denser media have particles that are closer together, allowing sound - wave energy to be transferred more quickly. The ground (solid) has particles packed more tightly than air (gas).

Answer:

B. Particles of matter are packed more tightly in the ground than in the air.
