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 grained Large crystals Ex: Granite
Magma reaches the surface as lava, then cools and hardens quickly Fine grained Small crystals Ex: 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 buildings Shale- used in ceramic tile
Coal- used for energy Limestone- fossiliferous Organic- made from remains of living organisms
Calcite Limestone 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
Gneiss Slate Have visible layers or bands
Quartzite Marble Uniform throughout (no layers)
