A. air is cooler than the ground.
B. ground is cooling faster than the air.
C. air has high humidity.
D. wind is blowing in the direction of the sound.

Respuesta :

The correct answer is A. air is cooler than the ground.

All of the other possible solutions would not cause refraction of sounds away from the surface, some of it would not influence the sound in any way. Sound waves travel slower through cool air and sometimes they disappear before even reaching the ground.
