Here's an overview of volcanoes presented in a coloring page format. It includes information on the locations of volcanoes, tectonic plates, shield volcanoes, cinder cones, stratovolcanoes/composite volcanoes, subduction zones, geothermal energy, thermal features such as geysers and fumaroles, the human impact of volcanes, Earth's composition, and a definition of volcanoes. All on one nice coloring page! Whew!
Also included are a crossword to accompany the coloring page if you'd like to challenge your students a bit more and a folder called "High Quality Coloring." This folder contains both a short presentation to help your students produce their best possible colored works and a scoring rubric.
