`color { maroon}ul{"Igneous Rocks"}`
Extrusive igneous rocks cool and solidify quicker than intrusive igneous rocks. They are formed by the cooling of molten magma on the earth's surface. The magma, which is brought to the surface through fissures or volcanic eruptions, solidifies at a faster rate.
`color{green} ✍️` Formed due to the cooling, solidification and crystallisation of hot and molten magma.
`color{green} ✍️` Igneous means 'firery' (from heat or fire).
`color{green} ✍️` Such rocks do not contain fossils or organic matter.
`color{green} ✍️` They are called as the primary rocks as all the other rocks are formed directly or indirectly from the igneous rocks.
`color{green} ✍️` They are hard, granular and crystalline rocks, less affected by chemical weathering.
`color{green} ✍️` There are about 700 different types of igneous rock.
`color{green} ✍️` Moreover, it does not have any fossil or does not form any strata or layers of lava,
e.g. of Igneous rocks-Granite, Basalt, Gabbro, Pegmatite and Peridotite.
Uses of igneous rocks:
`color{green} ✍️` Granite is used for building and construction because of its strong properties.
`color{green} ✍️` It is also used for head stones and kitchen counter tops.
`color{green} ✍️` Pumice is lightweight and has lots of air spaces.
`color{green} ✍️` It is used by cosmetic and cleaning industries to make things like excess skin removing stones.
`color{green} ✍️` It is also used in some toothpaste products because of its abrasive nature.
