Question

Write three or four sentences to describe the process by which the sound of a book dropped on a desk reaches your ear. (3 points)

Answer 1

Sound is a type of energy made by vibrations. These vibrations create sound waves which move through mediums such as air, water and wood. Sound wave vibrations 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.
