PRESENTATION OUTLINE
TYPES OF ROCKS IN THE ROCK CYCLE
BY: NICK WEAVER
This will be a Haiku Deck that describes what a makes a rock either an igneous, sedimentary, or a metamorphic rock.

IGNEOUS ROCKS
- Fire made rocks
- Formed by molten lava or molten magma cooling.
- Can have small or large crystals
- Could form into natural glasses
The slide is just a review of what igneous rocks are before the students will take a look at pictures of rocks where they need to try think about their physical characteristics and then be able to identify the rocks as either being igneous, sedimentary, or metamorphic rocks.

SEDIMENTARY ROCKS
- Formed by pressure, compaction, or cementation.
- Often found in bodies of water, or water once was.
- Often these rocks have layers or large "chunks" stuck in them.

METAMORPHIC ROCKS
- These rocks are formed by intense heat, pressure, or both.
- Often these rocks will have layers that are bent or twisted and look like obvious chemical changes took place.

WHAT TYPE OF ROCK IS THIS?
IGNEOUS ROCK
This rock is an igneous rock because as you can see it's crystals are very small, and it appears to have cooled and dried into a glass like appearance

WHAT TYPE OF ROCK IS THIS?
SEDIMENTARY ROCK
This rock is a sedimentary rock, because if you look closely you can see the layers that are formed overtime because of immense pressure and have become cemented together.

WHAT TYPE OF ROCK IS THIS?
IGNEOUS ROCK
This rock is an igneous rock because when it cooled large air bubbles called inside of it. This rock is called pumice and can actually float in water

METAMORPHIC ROCK
This rock is metamorphic rock, because if you look closely at the layers you can see how the layers are bent and twisted. This took place because of immense heat and pressure.

SEDIMENTARY ROCK
This rock is a sedimentary rock because as you can see large pieces of other rocks have been cemented together because of pressure.

WHAT TYPE OF ROCK IS THIS?
METAMORPHIC ROCK
This rock is a metamorphic rock. You can identify by the fact that you can see that immense pressure overtime has squeezed this rock together so that you cannot see any of its original properties of other rocks and minerals.

WHAT TYPE OF ROCK IS THIS?
SEDIMENTARY ROCK
This rock in sedimentary rock that is formed over a long period of time when the sand was under water and received a lot of pressure. Over time erosion from wind broke of pieces of rocks and sand and carried them away.
