A Tribute To Rocks
Welcome to TributeToRocks.org. We've created a tribute to rocks, because they deserve one! Now, you may be asking yourself, "What exactly is a rock, anyhow?" A rock is an object, large or small, commonly found anywhere outside, and made up of minerals. A mineral is a naturally occurring, homogeneous inorganic solid substance having a definite chemical composition and characteristic crystalline structure, color, and hardness. This includes such substances as copper, zinc, sodium, potassium, and iron. Since all rocks are composed of minerals, it's important to know a few things about them. For instance, let's review a few minerals in relation to Moe's Hardness Scale, which measures a mineral's resistance to scratching. The lowest and softest mineral on this scale is talc, commonly used to prevent diaper rash. It lands at number 1 on the scale. A diamond, the hardest mineral known to man, lands at 10 on this same scale, and because of this is often used in industrial purposes, such as drilling. My personal favorite mineral is quartz, which lands at 7 on Moe's Hardness Scale. It is the hardest common mineral, and different impurities or lack of them can make it asthetically pleasing. Here is a prime example of some quartz:
Different minerals combine in different formations to form countless varieties of rocks, and the world around us is full of them.To learn about the different ways rocks can be used, click here.
