Wanda and marita are drinking bottles of water. each girl sounds a different musical note by blowing across the top of her bottle. what is a good hypothesis that could lead to new experimentation? it is more fun to play musical notes with carbonated water than with normal spring water. if the lid on a bottle is tightly closed, then blowing across the top of the bottle will not make a musical note. blowing across the top of a bottle can make a musical note. if there is less water in the bottle, then the note played is lower because there is more air to move around.

ITS NOT C!

its actually D.If there is less water in the bottle, then the note played is lower because there is more air to move around.

D

Explanation:

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
