Why do sound waves move faster through the ground than through the air?

particles of matter are packed more loosely in the ground than in the air.

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

air doesn’t contain any particles of matter to transmit sound waves.

the elevation of the ground is lower than the elevation of the air space.

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

Explanation:

As we know that velocity of sound in a given medium is given by formula

here we know that

E = elasticity of the medium

= density of the medium

now we know that if we increase the density of medium then particles of matter are packed more which will decrease the speed of wave.

while is particles are tightly packed then it will increase the elasticity of the medium

So here if all particles are tightly bounded with each other then sound waves will move faster through the medium
