Plate tectonics is the theory that the earth’s crust is made up of plates that glide over a layer of mantle. a prediction of this theory is that the plates will move relative to each other as they move over the mantle. to test this hypothesis, a scientist places a marker on two adjacent plates to measure their movement over a decade. what would be the expected result of the experiment? how would you interpret the results if the scientist sees no movement?
