Place your paper on your desk landscape style.

Do a burrito fold (dividing the paper into thirds).

Do another burrito fold (dividing the paper into thirds again).

When you unfold, it should look like this.

Turn your paper to the side as shown and cut on the folds.

Cut both folds.

Cut through the folds on second flap also.

Now divide the top inside flap in half by cutting down the middle.

Cut the middle inside flap into THIRDS by making 2 cuts- dividing the flap into 3 equal spaces.

Cut the bottom inside flap in half by cutting a line down the middle.

Close it all up- turn it to where it opens like a book. Label as shown- Igneous, Sedimentary, Metamorphic

Open small flaps 1 at a time & draw lines to separate areas

Should look like this when you are done drawing lines to separate areas.

Form when molten rock (magma or lava) cools & hardens

intrusive

extrusive

Magma cools and hardens below Earth’s surface

Coarse grainedLarge crystalsEx: Granite

Magma reaches the surface as lava, then cools and hardens quickly

Fine grainedSmall crystalsEx: Pumice, Obsidian

Existing rock weathers, sediment erodes. Deposition in layers. Then compaction & cementation form rock

clastic

chemical

Non-clastic/organic

Made up of smaller pieces of rock

Sandstone- used in buildingsShale- used in ceramic tile

Coal- used for energyLimestone- fossiliferous

Organic- made from remains of living organisms

CalciteLimestone walls- building material, glass & paint

Dissolved minerals are deposited as water evaporates

When mineral crystals in existing rocks are changed by heat & pressure

Non-foliated

Foliated

GneissSlate

Have visible layers or bands

QuartziteMarble

Uniform throughout(no layers)
