The role of plate tectonics
WebbIn this paper, a two-class unit intervention using an explicit reflective approach to the teaching of nature of science was used in an undergraduate lesson on the history of plate tectonics. We measured the influence of the lesson on students' nature of science knowledge using the Student Understanding of Science and Scientific Inquiry instrument. WebbPlate tectonics has revolutionized the way we view large features on the surface of the Earth. Earth’s internal processes were previously thought to operate in a vertical fashion, …

Most agree that plate movement is the result of the convective circulation of Earth’s heated interior, much as envisaged by Arthur Holmes in 1929. The heat source for convection is thought to be the decay of radioactive elements in the mantle.
