Description
This lesson explains a theory on magma generation at hotspots called the mantle plume theory as well as possible ways of finding evidence to support the theory. The goal of this lesson is to introduce students to a theory that scientists are actively trying to evidence or refute. Through this students will learn about mantle tomography which helps scientists make predictions about the inside of the earth. Lesson duration: Approximately 25 minutes.
