1. What processes drive the rock cycle? Where do each of the different rock types form?

2.  Clastic  fragments of other rocks and minerals.  The size and shape of the rock fragments helps determine their names  Conglomerate, sandstone and shale

3.  Organic  Forms from organic shells or skeletal remains that cement into rock. fossiliferous limestone

4.  Chemical  Forms from chemicals dissolved in water  Limestone

5. + Heat and Pressure =

6.  Foliated-  Metamorphic rocks that have ribbon- like layers in their textures.  Gneiss (nice)  Common in NJ

7. Non-foliated Metamorphic rocks made of only one or two minerals and have no layering.  Marble  Limestone + Heat and Pressure = Marble

8.  Obsidian  Forms when magma comes to surface and cools = extrusive  Glassy, no crystals  Volcanic glass

9.  Granite  Forms when magma cools below the surface= intrusive

10.  Scoria  Volcanic rock  Many gas bubbles
