  • You know what, guys?

  • I just love rock music.

  • But we thought you love only one kind of rock.

  • The original ones. Us!

  • That's right! Weren't you supposed to tell your friends about us?

  • Ooops! You're right! I think I should take some break from Rock Music..

  • ..and tell you guys about the different types of Rocks.

  • Happy now?

  • Wohoo! Finally!

  • C'mon guys! We've got a lot to learn about different types of Rocks!

  • Zoom In!

  • There are three major types of rocks.

  • Based on their formation and they are..

  • Igenous Rocks.

  • Sedimentary Rocks.

  • and Metamorphic rocks.

  • Igneous Rocks!

  • The name Igneous is derived from the Latin word Ignis..

  • ..which means fire.

  • So Igneous rocks are formed when the molten matter inside the Earth..

  • ..called magma comes out of a volcano and later cools down and solidifies.

  • There are two types of Igneous Rocks.

  • When the Magma cools down and solidifies inside the earth's surface..

  • ..they are known as Intrusive Igneous rocks.

  • When the magma erupts above the earth's surface and solifidies..

  • ..Exstrusive Igneous rocks are fomed.

  • Pumice and Granite are some examples of Igneous rocks!

  • Sedimentary Rocks!

  • Sedimentary Rocks, as the name suggests are comprised of Sediments.

  • These sediments could be minerals, small pieces of plants and other organic matter..

  • ..that have been compressed and deposited over a long time.

  • These rocks can be generally found on ocean and lake beds.

  • And on rocky surfaces on the Earth's crust.

  • Sandstone and Coal are some of the Sedimentary Rocks.

  • Metamorphic Rocks!

  • When the igneous and sedimentary rocks are exposed to high temperatures..

  • ..and pressures, they undergo change.

  • And this process of changing from one form of rock to another..

  • ..is called Metamorphism.

  • But hey, that takes a long time.

  • Maybe thousands of years.

  • However this process doesn't melt the rocks..

  • ..but instead transforms them into denser, more compact rocks.

  • Slate and Marble are some examples of the Metamorphic rocks.

  • Trivia Time!

  • The upper segment of the Earth's crust..

  • ..is made of about 95% of Igneous Rocks.

  • The Taj Mahal in India is completely made of..

  • ..different types of Marble, a metamorphic rock!

  • See I told them all about you!

  • Doesn't that make you happy?

  • Yeah! Very Happy! Weehee!

  • So this is me zooming out!

  • Tune in next time for more fun facts.

You know what, guys?
