BBC schools-Rock cycle

I just love the BBC schools site.  There are so many good interactive links available.  Here's one from Bite size science. ROCKS AND WEATHERING  It's a nice little explanatory video of the rock cycle, cartoon images, not photos, but a nice explanation.  The Bite Size sites on the BBC are great for use with your IWB.  Check them out.
