Me out man 98 points! according to the theory of plate tectonics, 250 million years ago all of earth’s landmasses were clustered into one supercontinent, known as pangea. based on the past and current movements of earth’s plates, predict how the location of the continents might shift during the next 250 million years. do you think they’ll spread out, cluster together, or move in a combination of the two? what types of landforms do you anticipate forming as a result? what effect, if any, do you anticipate this movement will have on life on earth?
