When we look at the earthquake evidence for Plate Tectonics, one amazing feature is the Benioff Zoned earthquakes that show the dipping of one plate under another and then into the mantle. When an earthquake occurs it is measured by

Rocks of Ages
Description : Student activity where they calculate the speed of a moving tectonic plate by using the ages of rocks across the Hawaii Island chain. This is a great activity to show how hot spot evidence can provide us plate
