Today is International Rock Day and we"re giving due respect to these geologic wonders. It might seem odd to sing the praises of rock, but think about it. Rocks have been with humankind since the beginning. From tools to housing to weapons, they"ve been key to our survival. A period of our history was so reliant on rocks that it will be forever known as the Stone Age. We would not be where we are today without the many minerals found on our planet, so rock on!
