The Rock Cycle

Rock cycle: - One type of rock changes to another type under certain conditions in a cyclic manner. This process of transformation of the rock from one to another is known as the rock cycle.

When the molten magma cool; it solidifies to become igneous rock. These igneous rocks are broken down into small particles that are transported and deposited to form sedimentary rocks. When the igneous and sedimentary rocks are subjected to heat and pressure they change into metamorphic rocks. The metamorphic rocks which are still under great heat and pressure melt down to form to form molten magma. This molten magma again can cool down and solidify into igneous rocks.  

Rocks are useful to us in following ways:-

1.  Hard rocks are used for making roads, houses and buildings.

Stones are used in many games like seven stones (pitthoo), hop-scotch (stapu) etc.
