Sound is a form of energy that can be detected by our ears and can be used for expression and communications.
2.Sound are detected by our ears.
3.The external ear channels sound from around us and directs them into the ear canal. The sound makes the air in the ear canal vibrate. The vibrations are then passed to the eardrum. Then to the three tiny bones: Malleus, ineus and stapes.Then to the inner ear (cochlea).The inner year has a structure of many tiny hairs. The tiny hairs change the sound into electric signals that are then passed to the brain by Auditory nerves.]]> 2021-01-25 08:32:24 UTC https://padlet.com/tchr21770/Gases/wish/1120812020 https://padlet.com/tchr21770/Gases/wish/1120813804 Alyan khan

Sound is made when air molecules vibrate and move in a pattern called waves or sound waves.

An ear has an eardrum inside, connected to three small bones. The vibrations in the air make the eardrum vibrate, and these vibrations are passed through the three small bones (called ossicles) to a spiral structure called the cochlea. rehan6754 https://padlet.com/tchr21770/Gases/wish/1120834821 2021-01-25 08:38:45 UTC https://padlet.com/tchr21770/Gases/wish/1120834821
