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. |

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. |
|
Instructions
The students should plot the information in the green and blue columns on the graph paper provided (Plate Velocities Activity Graph Paper). Once the students plot the points they should draw a straight line of best fit (do not connect the points). The graph following the data set is an example of what the students graph should look like. Make sure the students are calculating the slope of the line and not of two data points. Also have the students compare their graphs to the image of the Hawaiian-Emperor chain. They should notice that both their graph and the image of the chain are roughly linear. The students will likely get different plate velocities because the fit their lines will be different. The plate velocity should be approximately 8 cm/year. |

Description
These are the instructions for the Plate Velocities Activity. After completing the Plate Velocities presentations the velocity of the Pacific Plate can be estimated using this data. |
|
Instructions
Use these instructions along with the data provided in the Plate Velocities Activity presentation and the Plate Velocities Activity Graph Paper to determine the velocity of the Pacific Plate. |
