Rock Cycle

igneous rock, sedimentary rock, and metamorphic rock. - Classifying Rocks Rock Classification Geologists classify rocks into three major groups depending on how they are formed: igneous rock, sedimentary rock, and metamorphic rock.

Rock Processes Review Igneous Sedimentary Metamorphic

5. Igneous Rock Serve and Enjoy Igneous Rock Recipe 1. Take some Minerals & Gasses – Mix well Place in oven (2,000 C) Add Heat Energy & Melt Quartz + Biotite + Feldspar 3. Change Rock to Liquid Phase (Magma) 4. Remove from heat, let it Cool & Crystallize (Intrusive/Extrusive) 5. Igneous Rock Serve and Enjoy Minerals + Heat

Sedimentary Rock Recipe 1. Start with existing rock at the Surface 2. Weather (Break Up) 3. Erode (Carry Away) 4. Sedimentation & Deposition 5. Compaction & Cementation Igneous Rock Sedimentary Rock © Beadle, 2009

Metamorphic Rock Recipe 1. Get some pre-formed rock – Igneous or Sedimentary will do & burry it deep underground. Granite (Igneous) 2a. Add a mild amount of Heat (Not too hot) 2b. Squeeze to Foliate + Pressure + Pressure 3. Cool & (Re)-Crystallize Gneiss (foliated) + HEAT Note: Add more heat for Igneous Rock 4. Metamorphic Rock

Rock Processes Review Igneous Sedimentary Metamorphic

Linear Process Connection Igneous Rock Cool & Crystallize (Extrusive) Rise to the Surface Cool & Crystallize (Intrusive) Change to Liquid Phase (Magma) Weather (Break Up) Erode (Carry Away) Take minerals & Add a lot of Heat to Melt Sedimentation & Deposition Metamorphic Rock Compaction & Cementation Cool & (Re)-Crystallize Sedimentary Rock Add Heat & Pressure (Not too hot) burry it deep underground

What is the Rock Cycle? -The process of rocks changing from one type of rock to another Igneous Rocks Any rock type can be changed into any of the other two and back again depending on conditions Sedimentary Rocks Metamorphic Rocks

mtn’s are granite= Igneous The rock cycle is an active process that you can see just about everywhere outside: The white tops of these mtn’s are granite= Igneous Weathering & Erosion are actively breaking down the mountains & creating sediment Deposition: minerals from the Granite spreading out as sand & clay! This makes the soil of the valley Underneath the surface, sediment is being compacted & cemented = Sedimentary
