This review material is meant to reinforce student understanding of the relationship between plate tectonics and the rock cycle. Although developed for students in the United Kingdom, it can easily be modified for any region on Earth. The activity involves students answering questions based on their knowledge of plate tectonics and the rock cycle and could be used as a homework assignment or individual project. A feature of the site is a link on the student page to a map showing all of the Earth's tectonic plates and their directions of movement. Educational levels: High school, Middle school
