What is a good lesson without a few random, may-never-use-again but totally interesting facts! A few fun facts about rocks and earth, here we go!
- The word “igneous” comes from the Latin “ignis” which means “fire.“
- Did you know that graphite (that stuff in pencils) and diamonds are both made almost entirely of carbon? But different conditions have formed them to be completely opposite!
- Pyrite might look like it will make you rich but that yellow shiny is not actually gold. That’s why it is also called “fool’s gold”.
- Quartz watches ACTUALLY have pieces of quartz in them! When jolted with electricity, the quartz vibrates in a specific rhythm and keeps great time.
- When lightening strikes beach sand, it is so hot it melts the sand into a glass called fulgurite.
- Meteorites are rocks from space. They help us learn all about the solar system.
- Isn’t this a beautiful rock? Wouldn’t you love to take it home and add it to your collection? Well, that probably is not the best idea. These green crystals have Uranium and slowly put off radiation as they sit on your shelf.
