Rocks
There are many kinds of rocks. They come in
a great variety of shapes, sizes, colors, and
textures. Rocks also have some things in
common. They are made naturally and are
made of smaller particles and minerals that are
stuck together. They are made of
specific chemicals.
What do rocks have in common?
a. They are all the same size
b. They are all the same color
c. They are made naturally
d. They are the same shape
Factories use different processes to make
things. They use heat, water, and force from
machines to form their products. Earth is like
a giant rock factory. Wherever you are right
now, if you could dig down far enough, you
would find rocks being made deep inside the
earth.
2. How is the Earth like a factory?
a.
b.
c.
d.
They both have machines
They both use the same process
They both make rocks
They both make things
Rocks can be divided into three rock types.
They are igneous, sedimentary, and
metamorphic. The groups describe how they
are made.
3. Rocks are divided into which three groups?
a. igneous, sediment, metamophose
b. sedimentary, igneous, metamorphic
c. ignite, metamorphic, sediment
d. sedimentary, ignite, metamorphic

Igneous
•These rocks were made from cooled
magma or lava
•Igneous literally means “From Fire”
http://www.learner.org/interactives/rockcycle/change2.html
• The texture depends on how fast the rock
cools
– Quickly cools- smooth texture
– Slowly cools- bumpy or rough texture
Sedimentary
http://www.learner.org/interactives/rockcycle/change3.html
These rocks are made from layers of
sediment that has been cemented
together
Types of sediment:
• They are soft and
crumbly, made of
layers
• Examples are
sandstone, limestone
and shale
sand, shells, pebbles, bits of rock,
minerals, organic matter (from
living things), or fossils
Metamorphic
http://www.learner.org/interactives/rockcycle/change.html
• Metamorphic rocks are formed
when existing igneous or
sedimentary comes under extreme
heat and or pressure (“squeezing”).
• Examples are Marble, and Slate
Two groups based on
internal structure:
 foliate- bands or zones
of same material
Non-foliated- no visible
bands or zones
Metamorphic
• These rocks have
literally
“Metamorphosed”
(changed).
• That means they started
out as one thing and
became something
completely different.
• They are formed
underneath the surface of
earth
