Dear candidate,

Sound also acts like a wave. Mountains and deep valley areas are surrounded by the rocky surfaces of mountains, trees, etc and the area among them is also dense. Thus, when the sound wave touches the rocky surface, it comes back, and since there is no specific direction, it echoes everywhere.
