The Rockin' Life Of Marly
Metamorphic Rock
Hi, I'm Marly the metamorphic rock. I was formed by time, pressure, and heat.
Now the melting inside the Earth is melting me into the molten material, magma.
Lava is magma that comes out of Earth.
I'm now shooting out of this volcano as lava.
I've started to cool and crystallize! Aren't I shiny?
Igneous Rock
(I'm now an igneous rock!)
Weathering is the process that breaks down rocks and other substances.
Oh No! Now I'm beginning to weather!
Sediment is broken up pieces of rock.
SEDIMENT
Now I'm spread everywhere. That means that I'm . . .
I am get chemically weathered. Chemical weathering is when rock is broken down through chemical changes.
I've become so small because I've been weathered by acid rain,
Acid rain is rain made by pollution in the atmosphere.
I'm getting weathered mechanically, which means that rock (me), is getting physically broken into smaller pieces.
This is an example of abrasion because rock (me) is being worn down by other rock. Ouch!
!
Now I'm being turned in to rock again through the cementating and compaction of these waves.
Sedimentary Rock
Yay! I'm now whole again thanks to those waves.
Sedimentary rock is material dropped on another.
TIME!
HEAT!
PRESSURE!
Hooray! I'm my self again. Good ol' Marly the metamorphic rock.
THE END
For now . . .
