Remember when pet rocks were cool (for what reason? I have no idea!)? Or when you first learned how rocks were formed? So whether or not you are a geology geek, you can still enjoy Old Rock Day today.
QUICK! What is the oldest rock on Earth? Yeah, I have no idea either! But supposedly the oldest rocks found date back a little more than 4 BILLION years!
Rocks could be anything from a mountain, boulder, or a stone to a gem! So just have fun promoting a unique occasion like Old Rock Day.
