Quizplus · Accepted Answer

This phenomenon is known as refraction, which occurs when sound waves pass through a medium with varying density. When sound travels faster higher above the ground than below, it encounters a gradient in density at the boundary, which causes it to bend downward towards the denser layer of air closer to the ground. Therefore, the correct answer is B) downward.
