How many different rocks and minerals are there Identifying Rocks and MineralsTypes of Rocks. There are three different types of rocks Igneous, Sedimentary, and Metamorphic. The difference between each type is in how they are formed. What are the types of rocks and their examples Rocks Igneous, Metamorphic and Sedimentary. Andesite. Basalt.
Lets find out how many types of rocks are there. Even if you have only had the chance to examine the pebbles in your garden, you will probably have seen that the color, shape, and hardness of the pebbles can vary quite considerably. Remember that soft, white, crumbly chalk and hard, black basalt is both rocks.
Abundant quartz, on the other hand, are the types of rocks granite that end up forming feldspar rocks. Granitoids are types of rocks granite that are known to have dark minerals. They are known to be hard too as they contain many different kinds of minerals. However, there are types of rocks granite that can be light colored as well.
