This Kind Rock Cycle NOT THIS KIND Do Now 1) Move to each station that is set up with rocks. Spend two minutes at each station and list at least 4 characteristics of the rocks that you see. 2) Write down the definition for a mineral. 3) What is the difference between a rock and a mineral? Count off by 8 and get into groups. Try to arrange the rock cycle with the pieces given. Rock Definitions Igneous Rock: – Magma and Lava cools and hardens to form Sedimentary Rock: – The accumulation of various types of sediments compacted and cemented together Metamorphic Rock: – Heat and pressure cause existing rocks to change their minerals and/or shape Intermediate States Magma/Lava Sediment Processes 1. Cooling/hardening 2. Compaction/Cementation – Compaction: weight of overlying sediments causes pressure pushing sediments together – Cementation: minerals dissolved in water are transported and left behind to cement sediments together Processes 3. heat/pressure 4. melting 5. weathering – Change in the physical form or chemical composition of rock materials exposed at the surface What does the rock cycle that you created tell us about the fate of rocks? How are rocks classified? How does this different from the classification of minerals? Can you figure out which station held which of the three types of rock?
