Rocks are aggregates of minerals, rocks are major of three types:
- Igneous Rocks
- Sedimentary Rocks
- Metamorphic Rocks
Igneous rocks are created when lava cools down and solidify in rock.
The metamorphic rocks are made by the subjection of igneous rocks and sedimentary rocks under high pressure and temperature.
The sedimentary rocks are created by continuous deposition of minerals, earlier rocks, and animal.
Example of igneous rocks are granite and made up of a mixture of element example SiO2 and Al2O3.
Examples of sedimentary rocks are breccias and siltstone and of metamorphic rocks are marbles.
