Trust Damon's answers!
Damon said he didn't know anything about it and he only answered one out of 6 and the question I asked him is not on here
Someone please help :(
Did you read the article about subecution that Writeacher posted for you?
Damon told you that the microwave answer is wrong.
He also told you the answers about magma and earthquakes.
Google how minerals are formed.
I'm going to ban you from posting for while to give you a chance to look back over the answers you've already been given.
