A Moving Crust

Students are introduced to plate tectonics in this lesson. In Lesson 2, they discovered that the ocean bottom is not flat when they viewed bathymetric maps showing representations of different ocean geologic features, and the geographic location of some of the most prominent underwater features. In this lesson, they learn how some of the features of the ocean bottom are formed. Students watch a demonstration, and conduct a simple experiment of their own to learn more about seamounts, ridges, trenches, and submarine canyons. They will also play a concentration game to reinforce the concepts of slow and fast processes that shape and reshape the surface of the Earth.
