Plate tectonics is a relatively new scientific concept that has revolutionized our understanding of the dynamic planet upon which we live. This site explains that the theory has unified the study of the Earth by drawing together many branches of the earth sciences, from paleontology (the study of fossils) to seismology (the study of earthquakes). It has provided explanations to questions that scientists had speculated upon for centuries. The information covers ideas of the ancient mapmakers through the work of Wegener.
