Quizplus · Accepted Answer

Future tectonic events, specifically subduction zones, will thicken the crust along the west coast as oceanic plates are pushed under continental plates. Similarly, the crust along the east coast will thin as the Atlantic Ocean widens and new oceanic crust forms. Therefore, option C is the best choice. The other options are incorrect based on tectonic plate movement and would not result in the predicted changes in crust thickness.
