This is a very interesting video examining major issues with the conventional theory of plate tectonics that are better explained with an expanding model of the Earth. Thus instead of complicated models of large plate movements, a simple mechanism of expansion would be required. This is a very interesting look at geology that has broad implications, especially in regards to the effects of a changing gravitational force with the size of the Earth throughout historical times. Such gravitational changes may also better explain the very large size of dinosaurs and other large extinct animals.
