Science Project Due tomorrow

PLEASE ANSWER SOON THANK YOU
I am doing a project on metal corrosion. I just have a few questions.
1. Why do some metals corrode more than others?
2. When I put copper and brass in saltwater, the water turned blue. Why is that?
3. Also, the most serious change occurred when the metal was a little bit out of the water. Do you know why this is?
