NO LINKS OR ELSE YOU'LL BE REPORTED!Only answer if you're very good at science. Why is a sound wave a mechanical wave?​

a sound wave moves through air by displacing air particles in a chain reaction, sound energy is associated with vibrations created by a vibrating source, that requires a medium to travel, which makes sound energy a mechanical wave

Explanation:

hoPE that helped :)

Mechanical waves move "things"...they require a medium (whose molecules are the "things") to transmit their energy. Sound uses air molecules most of the time. It can use water molecules as well.
