Types of Rocks
Talk with your table!
• What do you already know about rocks?
Rocks are divided into 3 types…
• IGNEOUS
• SEDIMENTARY
• METAMORPHIC
Add to your notes:
Types of Rocks
Igneous
Sedimentary
Metamorphic
Igneous Rocks
Definition Information:
•Igneous literally means “From Fire”
•These rocks were made from cooled
magma or lava
•Intrusive igneous= from magma
•Extrusive igneous = from lava
Other Key Facts Information:
• The texture depends on how fast the rock cools
– Quickly cools- smooth texture
– Slowly cools- bumpy or rough texture
• They are very hard and can have crystals
• Examples are basalt and granite
Discuss with your table….
….the differences between the igneous rocks
made from magma and the igneous rocks
made from lava.
What are they called?
Which will cool faster?
Where will they form?
Etc!
Sedimentary Rocks
Definition Information:
These rocks are made from layers of
sediment (weathered rock) that has been
cemented together.
Other Key Facts Information:
• Types of sediment: sand, shells,
pebbles, bits of rock, minerals,
organic (from living things)
matter, or fossils
• They are soft and crumbly, made
of layers
• Examples are sandstone,
limestone and shale
Discuss with your table…
…how would the type of sediment affect the
appearance of the sedimentary rock they
create?
Colors?
Texture?
Location?
Etc!
Metamorphic Rocks
Definition Information:
• Metamorphic rocks are formed
when an existing igneous or
sedimentary rock comes under
extreme heat and pressure
(“squeezing”).
• These rocks have literally
“Metamorphosed” (changed).
– That means they started out
as one thing and became
something completely
different
Metamorphic Rocks
Other Key Facts Information:
*Two groups based on internal structure:
Non-foliated
Foliate- bands or zones of same
material
Non-foliated- no visible bands or zones
*They are formed underneath the surface
of earth
*Examples are marble and slate
Foliated
Discuss with your table….
….How are metamorphic and sedimentary
rocks similar? Different?
