Rock Cycle
Three Types of Rocks
•
Igneous…
formed from magma(inside
earth)/lava(outside earth) that has cooled
and hardened
Three Types of Rocks
•
•
Sedimentary…
formed by sediments being
cemented/pressed together
Three Types of Rocks
•
Metamorphic…
formed from rock that is changed by
heat and pressure
What can happen to rocks???
Three things can happen to
EACH type of rock

Weathered/eroded and broken into fragments
(sediments)
then it will erodecement/compress

Undergo heat and pressure
then it will change

Melt
then it will cool & crystalize

can be cycled and cycled.
 One rock can turn into another or form
new rocks

Rock Cycle Song
(Sing to the tune of "Row, Row, Row Your Boat")
SEDIMENTARY rock
Has been formed in layers
Often found near water sources
With fossils from decayers
Then there's IGNEOUS rock
Here since Earth was born
Molten Lava, cooled and hardened
That's how it is formed
These two types of rocks
Can also be transformed
With pressure, heat and chemicals
METAMORPHIC they'll become.

 What

is the rock cycle?
The rock cycle is a series of processes that
change one type of rock into another type
of rock.
