Large quantities of tritium were released into the atmosphere in the 1950s and 1960s during atmospheric nuclear testing. this tritium fell back to earth in precipitation. assume that the precipitation joins surface runoff that eventually empties into the ocean. how would you expect the tritium to get to the ocean? a. by evaporating b. by recharging an aquifer c. by percolating d. by entering an open watershed

D. By entering an open watershed

Explanation:

A watershed is a place where the water arrives and enters directly into the water cycle, by doing this the water enters a cycle tha will end up in the oceans and rivers after a certain amount of time and processes, so the tritium that was realeased into the atmosphere must go back into the ocean because it was falling into a open watershed and then into the water cycle.
