Amarine scientist concluded that the canary islands were not formed by volcanic activity because his data showed that the fault on which the islands lies was inactive during the islands' formation. another scientist disagrees with his measurements and provides data showing that the fault was active at that time. how does this disagreement contribute to the scientific process?

By the disagreement they can brainstorm on which aspects does their finding is a bit inconclusive. By figuring out the loop holes in each argument they can now generalize the correct and accurate finding regarding the issue. Maybe they need to verify the data the collected to counter check their conclusions.
