Rocks are in general made up of two of more minerals, mixed up through geological processes. For example granite is an igneous rock mostly made from different proportions of the minerals quartz, feldspar and mica, as interlocked crystals. A sandstone is a sedimentary rock that can also contain quartz, feldspar and mica minerals, but as grains
Gemstones are minerals and not rocks, as they are popularly addressed. A mountain is essentially a rock. Sand is a result of constant weathering of rocks. There are more than 4000 minerals identified by geologists and scientists. But this is not the maximum number as there are new reports that suggest the discovery of new minerals annually. Minerals are further divided into metals and non
Similar to minerals, the formation of rocks is a natural process. However, it may be interesting to know that rock is a composition of two or more mineral grains.
