A 22-slide set provides pretty much everything you need to teach the rock cycle except the actual specimens. All of the slides contain graphics or photographs to help describe the process, and most even have links to educational videos. You will need to make a couple of minor adjustments: two slides have pictures that need resizing, and references are made to the teacher who designed the slides and to a specific textbook. Nevertheless, you may want to bury the other slide shows and uplift this one into your curriculum!
