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.
