ROCKS AND FOSSILS
SUPPOSE 4 BIRDS FLEW OVER THIS ROCK A LONG TIME AGO. IT DROPPED A SEED ON THE ROCK. A TREE NOW GROWS IN A CRACK OF THE ROCK. HOW COULD THE TREE AND ITS ROOT CHANGE THIS ROCK?
ROCKS DO NOT ALWAYS STAY THE SAME. LOOK CLOSELY AT THIS MOUNTAIN ON THE SIDES AND AT THE BOTTOM ARE SMALLER ROCKS. THEY HAVE BROKEN OFF THE MOUNTAIN. THE ROCKS OF THE MOUNTAIN ARE BEING CHANGED. THEY ARE BEING BROKEN DOWN. BREAKING ROCKS INTO SMALLER PIECES IS CALLED WEATHERING.
