The Big Question: What processes within Earth cause geologic activity? Students use a variety of methods, including software, the Internet, and two-dimensional maps to observe differences in topography and earthquake and volcano patterns. In the process, they learn about the structure of Earth, the theory of plate tectonics, interaction of Earth systems, and the history of Earth. By connecting all of the information gathered through readings, investigations, and collaboration with others, students are able to create an explanation for the changes happening in the region of specific Earth structures they are studying.
