The material of the continents is older than that of the ocean floors. Design a model that illustrates sea floor spreading and explains the idea that continents are older than ocean basins. Utilize available core data to explain the age of the sea floor using magnetic banding and radioactive dating procedures. The materials of the crust have been recycled over and over many times. Discuss the theory of plate tectonics and different plate boundary types and how they interact.
Fossils show how life has evolved within the framework of the environment.
Discuss different conditions that favor or hinder fossilization. Show how present day organisms are adapted to their environments and fossil organisms were likewise adapted to individual environments of their time. Fossil distribution shows how life has been shaped by plate movement. Using the idea of plate movement show how climates can dramatically be changed thereby creating new adaptive zones where new species can develop. Evolution is the theory that explains how life has changed through time.
