Today is all about Rocks.
For today’s post, I had to ask myself. What IS a rock, exactly? And how is a rock different from a gem or a mineral? Here is what I found. Pretty basic stuff here – I’m figuring it out – so if you are more knowledgeable, I’d love for you to add some bits to the comments!
Mineral – A mineral is a substance that is formed together from specific crystallized matter (of the same physical composition).
Gem/Gemstone – A gem/gemstone is a polished mineral, of one specific type of matter.
Rock – A rock is an aggregate of minerals that does not have a specific mineral composition, but usually a variety of different minerals combined).
Geode – According to RocksandMinerals4u.com, a geode is like “the Tootsie Roll Pop(r) of the geology world: it’s a mineral inside of a rock. (The image in this post is a geode.)
Some rocks, such as lapis lazuli, are classified as gemstones, even though they are rocks by this definition.
Some may argue whether rocks are alive or dead. My vote is that they are alive. They do evolve over time as this article in the Economist explains. Or, if you read this article you might define life differently and think that perhaps rocks aren’t alive. I think that the jury is still out on this idea. What do you think?
