Are you Ready to RockS
Jimmy Has a Pet Rock…
Jimmy Has some
questions about
his Pet Rock
Willy.
It seems different
from the other
kid’s pets.
He wants to
know what Willy
is and Where
Willy came from.
Does Willy have
a family?
Willy is a Rock…
Not a Giant Lady Bug.
What is a Rock?
Rocks are composed of minerals. Rocks
can be composed of a large variety of
minerals or just one mineral. Although
over 3500 minerals have been identified,
some of the earth's minerals are
exceedingly popular and fewer than 20
minerals compose more than 95% of the
earth's crust.
All rock starts out as Magma
Where did Willy Come From?
Jimmy is a Product of Love…
MOM
DAD = Jimmy
Willy is the product of the Rock Cycle
The Rock Cycle?
• The Rock Cycle is the name for the process
used to describe the formation of the variety of
Rocks found on our planet.
• There are three different ways rock can be
created on earth and thus there are three main
classifications of rock. These rock
classifications are –
1. igneous
2. sedimentary
3. metamorphic.
Igneous Rock
At one point Willy was an Igneous Rock
?
•The word Igneous comes from Latin and means “Fire Formed”
•Igneous Rock forms when Magma (molten liquid minerals) is cooled either
below, or above, the earth’s surface.
• All rocks on earth were originally igneous because the cooling of Magma is the
only method entirely new rocks can be formed.

Igneous Rocks
Granite is a type of Igneous Rock commonly used in the
construction of buildings, monuments and tombstones.
Basalt is another type of igneous rock commonly used in
road building materials.
Is Willy an Igneous Rock?
Not Anymore.
Like Jimmy, Willy has undergone some changes.
Sedimentary Rock
Sedimentary means “formed by settling”
Key Concept Erosion
•Rocks are weathered and eroded into tiny particles
which are then transported and deposited. These
small pieces of rock are called sediments.
•Sedimentary rocks are formed by the cementing,
compacting, and hardening of existing rock and the
bones, shells, and pieces of formerly living things.
•Sediments are cemented together and compacted and
hardened over time by the weight and pressure of up to
thousands of feet of additional sediments above them.
Eventually, the sediments become solid sedimentary rock.
This is why you
sometimes find
fossils in rocks.
Sedimentary
Rock Song
Sedimentary Rocks
Sandstone is a common Sedimentary
rock used in the house building
industry.
Limestone is another common
Sedimentary Rock.
Shale is another type of
Sedimentary Rock. The
sediments that create Shale are
smaller than .06 mm.
Metamorphic Rock
The name Metamorphic comes from the Greek to "change form”
•Metamorphic rock is formed by applying great pressure and
temperature to existing rock converting it into a new distinct type
of rock.
•Igneous rocks, sedimentary rocks, and even other
metamorphic rocks and be modified into metamorphic rocks.
•Metamorphic rocks are usually created when they come
•
under extreme heat and pressure such as the pressure
caused by being under many thousands of feet of bedrock
or through being crushed at the junction of tectonic plates.

Rock Song
Metamorphic Rocks
Slate is a common metamorphic rock. Slate
is formed when Shale is put under pressure
with temperatures of a few hundred degrees.
Marble is a common
metamorphic rock. Used as a
building material.
So Jimmy….
I hope we have answered some of
your questions about who Willy is,
where he came from and how he has
grown into the unique Pet Rock he is
today.
Just remember to take good care
of Willy. During his existence so far
he has been cooled from Magma,
been crushed, pressurized,
eroded, transformed and even
painted.
Remember….
It’s a Rock CYCLE
•All three rock types can all be transformed into
Metamorphic Rock
•Any Rock Type can be Eroded into Sediments
•Any Rock type can be Melted back down to
Magma to begin the process all over.
Igneous Rock
Rock formed when magma cools
above or below the earth’s crust.
Sedimentary Rock
Rock formed out of pieces of rocks
and other materials that have been
compacted and hardened together
Metamorphic rock
Is formed by applying great heat
& pressure to existing rock
converting it into a new distinct
type of rock.
