By studying the distribution of different types of fossils, geologists have determined that some tectonic plates have traveled great distances. Evidence to support this is that -
A. fossils of organisms that lived in warm climates have been found in arctic environments.
B. species of organisms in the fossil record have changed over geologic time.
C. some fossilized organisms have only been found on only one continent.
D. the oldest known fossils, found in the deepest rock layers, represent ocean organisms.
