Name the three types of sedimentary rock

• extrusive, foliated, non-foliated

• bioclastic, chemical, intrinsic

• clastic, bioclastic, chemical

• igneous, metamorphic, sedimentary

Define weathering

• the dropping of sediments

• the process of removing the sediments (wind, water, etc.)

• squeezing layers of sediments together

• any process that breaks rocks into smaller pieces (sediment)

Where does the heat come from to create metamorphic rock

• Earth's core

• rocks

• air

What are the types of rocks?

• igneous, metamorphic, sedimentary

• clastic, chemical, bioclastic

• foliated, non-foliated

• intrusive, extrusive

How is an igneous rock formed

• heat and pressure

• 5 step formation

• magma or lava cools and hardens

How is a sedimentary rock formed?

• heat and pressure

• 5 step formation

• magma or lava cools and hardens

How are metamorphic rocks formed?

• heat and pressure

• 5 step formation

• magma or lava cools and hardens

Describe how the cooling rates affect the crystal grain size

• longer to cool=larger crystal sizes

• quicker to cool=smaller crystal sizes

• longer to cool=small crystal sizes

• quicker to cool=large crystal sizes
