What must take place for copper metal to be oxidized? someone pls ! i can't seem to find the answer in my book either and its frustrating.

1) describe the physical layout of the ocean floor ? 2) explain how the dumbo octopus swims differently than other octopus species and why this would be an advantage in the aphonic zone . 3) why are the types of organisms that live at each underwater hot vent so dramatically different ?
