Sound Explanation :)

Explanation template:
For inquiry this term we are studying ‘sound’ This explanation will explain you all about sound. Sounds items include musical and instruments. Have you ever wonder what sound is well this explanation will hopefully tell you all about it. Travel waves when it hits your ear drums it vibrate one another.  


If a material is hit and begins to vibrate, it travels through the sound waves and hits your eardrum. Once it hits your eardrum, it continues to travel to the brain which transfers it into a knowable sound. Sound travels faster through dry air then through moist air. You would hear the sound of an aeroplane travelling in the sky much more quickly on a hot day then on a cool day.

If the world had no sound it would be really difficult because sound is really good by teaching people and showing people what to do if we were stuck. If there wasn’t any sound at all It will  not really matter because we would know how to do sign language to each other. So we wouldn’t know anything about sound, but luckily we have sound because its easy for us and people that can’t hear sound so they  use sign language and it not difficult for them.
