 Hotspot Lesson: Plate Velocities - Introductory Lesson
 File Name w01.d02.783.hotspots.ppt Data Type presentation Computer Program Microsoft PowerPoint 2003 File Size 18.87 MB - 1 file Expert Level High School (Grade 9-12) Contributor ERESE Database Team Source Jamie A. Russell Resource Matrix The Formation of Seamounts
 Description This lesson defines hotspot volcanoes and the major contributor to the theory. It also discusses the importance of the hotspot theory and how hotspot island and seamount chains can be used to determine absolute plate motion. The goal of this lesson is for students to gain an understanding of hotspots and their useful applications in geosciences. Lesson duration: Approximately 35 minutes.

 Hotspot Lesson: Plate Velocities - Activity
 File Name w01.d02.784.plate.velocity.activity.ppt Data Type presentation Computer Program Microsoft PowerPoint 2003 File Size 7.85 MB - 1 file Expert Level High School (Grade 9-12) Contributor ERESE Database Team Source Jamie A. Russell Resource Matrix The Formation of Seamounts
 Description This activity provides the students with a data set of ages of some of the Hawaiian Volcanoes and seamounts and how far they are from the active volcanism (considered to be the location of the hotspot). By plotting the data on a graph and fitting the data with a line of best fit, the plate velocity can be estimated by taking the slope of the line.
