Rocks are our resources

          We use rocks in many different things. We use them in saws to make them cut better. The rock we use to make some saws cut better witch is not in all saw blades is Platinum. Platinum is also used in the cones of some missiles for a better tip. They use platinum because it is a sturdy metal. Metal is considered a rock witch also means we us rocks in many house hold items. Some people don’t realize how important rocks are but they are one of our main materials.

             For space shuttles we use rocks so it can reenter the earth’s atmosphere. The rock makes it so it can withstand the heat without being damaged. And if damaged not badly. So you can see that rocks are our resources.
