Answer 2

Answer:

sound is a type of energy. made by vibration. when an object vibrates it causes movement in the surrounding air molecules. these molecules bump into the molecules close to them which causes them to vibrate as well .

Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear. These bones are called the malleus, incus, and stapes.
