Sphinx’s Riddle 2

Another famous riddle attributed to the Sphinx is I speak without a mouth and hear without ears. I have no body but I come alive with the wind. What am I? The answer to this riddle is an echo. Echoes, speak by repeating sounds without a mouth, hear by receiving sounds without ears and are created by the reflection of sound waves off surfaces, particularly walls or mountains activated by the movement of air (Wind). @WaterWiseDefenders
