Well first you wonder how are rocks created? and so i will tell you how. There are three different types of groups of rocks Sedimentary, Metamorphic, and Igneous. Sedimentary rocks are formed by broken by winds and water then get washed into rivers, lakes etc. Then it forms layers that hardens and forms rock. Metamorphic rock is formed by rocks under tons of pressure which forms heat and makes it change to metamorphic rocks. Igneous rocks are formed by magma cooling forming igneous rocks. This is called the rock cycle it just keeps on going on and on it never ever stops.

One other question that we ask ourselves is can rocks be minerals? And yes they can. One of them is Quartz. Some really cool rocks are pumice it is my favorite! because pumice can float on water. So if you think that rocks can't float you are wrong this one can! And Marble for example is used in many statues. If you go to Greece you will find lots of it there. And you can find sand stone on the sides of cliffs near the ocean.
