I really have a passion for rocks. Being in Earth/Space Science this year, I'm well-acquainted with geology; I have quite an interest in metamorphic rocks. Despite my interest in geology, there's no doubt that my science teacher has much more of an interest in the subject than myself; for whatever reason, most concepts just can't stick in my head - probably because I'm busy texting in that class. I think I'll address each major class of rocks; Metamorphic, Igneous, and Sedimentary.
Sedimentary is almost like the unwanted one in the family; it seems like nobody really takes much of an interest in them. I suppose I can see why through some people's points of view - it's just a bunch of sediments (as the name states) compressed together into a rock. But people fail to notice the interesting aspects of all of the possibilities this may offer; there's a wide variety of sediments that can come together and make a new rock. Just thinking about the possibilities - the endless combinations - makes me excited. Sometimes I take a few minutes out of my day and think about the coolest-looking sedimentary rock I can think of. Usually people view sedimentary rocks as just sand, but dirt can also be used. See what I mean?
The fact that sedimentary rock can be made so easily is the other thing. Metamorphic or igneous rocks can also later become sedimentary - if the rock is broken up into sediments. Put a little bit of igneous, metamorphic, and some other sediment, and you have one individualized rock right there. And it's not just the substance that can affect it; the quantity can too. Putting more metamorphic rock sediments than sand can have an entirely different effect on the rock's appearance - and as should be obvious - and the general composition. Aren't sedimentary rocks just so exciting?
Then comes igneous rocks - quite the hot topic. There's more to them than just rocks coming from volcanoes; they're rocks that can form entire islands - Hawaii for example. These rocks provide some of the lands that we now live on. If you think about it, this makes volcanoes invaluable, and not just that geographical land form that covered Pompeii in ash. That event definitely blemished the volcano's credibility, but this might just bring them back into the modern world. Just think of what these rocks can do with the world; they'll create island after island, until the entire earth is covered in igneous rock. It will be like Pangaea all over again.
But igneous rocks do more than just take ov- err, make new land forms, they also build upon preexisting ones. Anyone who lives in Hawaii can tell you that constant eruptions have allowed Hawaii to expand slowly but surely. Our continents grow larger with each eruption, whether it's underwater or on land. Just think of what the world will be like millions of years from now. If global warming is legit, then the expanding land will conflict with the melting glaciers, making a proverbial struggle between the two. Doesn't that just sound exciting?
And then we have metamorphic rocks; the butterflies of geology. Once an ugly sedimentary or igneous rock, it's become a beautiful metamorphic rock. As far as I've really seen, they don't contribute much, except be complete and total trolls and just change every now and again. But the methods of how they change? Quite interesting if you ask me. Thinking about the intense heat or pressure that those rocks have to endure to become beautiful...it's really quite touching. It makes you think twice about when you see a girl in pain because she's trying to look beautiful. Just like that girl, those rocks are going through Hell just to become beautiful things.
As should be obvious, I love metamorphic rocks most. I love beautiful things, and those rocks are the super models of geology. They exhibit sheer will and determination to become the best that they can be. For those lesser sedimentary rocks and igneous rocks, it's survival of the fittest. The fittest become the coveted metamorphic rocks. Like all beautiful things, they don't do much; they just keep on being beautiful.
I'd say this wraps up my general feelings on rocks.
