Rocks and Minerals
The building of your school, your residential complex, etc. consists of rocks and minerals. Furthermore, there is a huge treasure chest of rocks and minerals inside the planet earth. Have you ever wondered how rocks are different from minerals?
They are resourceful parts of our day-to-day life. A few examples of some of the rocks and minerals that we use in our daily life, are cement, gold, granite, pumice, etc. Let us discuss rocks and minerals and their meanings.
A substance that is hard and inorganic in nature is called Rock. The formation of rocks is a natural process similar to minerals. However, it may be interesting for you to know that rock is a composition of two or more mineral grains. Rocks have different shapes, sizes, and textures. Rocks have been categorized into three types by the geologists, they are- igneous, sedimentary, and metamorphic rocks.
Examples are Igneous - Granite, Sedimentary -sandstone and limestone, Metamorphic-marbles and slate, etc.
Using a magnifying glass if you look at a piece of rock, you will notice that it is made up of small grains called minerals. Minerals are building blocks of rocks. The food we eat has traces of the presence of iron, calcium, and potassium in it. There are two types of minerals - metallic and non-metallic. Examples of Metallic minerals are magnetite and bauxite. Mica, quartz, calcite, gypsum are examples of non-metallic minerals.
