Principles of Plate Tectonics
"The Earth is composed of a mosaic of thin rigid plates (pieces of lithosphere) that move horizontally with respect to one another"
"Plates interact with each other along their plate boundaries"
"Plate boundaries associated with tectonic activity (mountain building, earthquakes, active volcanoes)"
