All of you know that Rocks are the solid mineral materials forming a part of the surface of the earth and other similar planets. Have you know that ROCKS can RECYCLED ?

Here are some Important Points about Rocks.
  • Four realms of the world, namely lithosphere, hydrosphere, atmosphere and biosphere.

  • Lithosphere is the top most and noteworthy layer of the earth.

    Classification of Rocks

    Rocks which classified into three types

    1. Igneous Rocks

    2. Sedimentary Rocks

    3. Metamorphic Rocks

  • Igneous Rocks - The igneous rocks formed by the consolidated of molten magma. These rocks are also called as the ‘Primary Rocks’ and all other rocks which found on Earth formed from these rocks.

  • Sedimentary rocks - It formed by the sediments derived and deposited by various agents. Due to the case of high temperature and pressure, the not disturbed sediments of long period cemented to form sedimentary rocks.

  • Metamorphic Rocks - the Igneous and sedimentary rocks get altered from its original shape due to high temperature and pressure,

  • These new rock called as metamorphic rocks
