Rock Cycle In your notes… Take out a BLANK page in your notes What is a rock? How is it different than a mineral? Give 4 characteristics of every rock… 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? Rock Definitions Igneous Rock: – Magma and Lava cools and hardens to form Sedimentary Rock: – The accumulation of various types of sediments compacted together Metamorphic Rock: – Heat and pressure cause existing rocks to change their minerals and/or shape #1 Intermediate States: Lava & Magma Magma is still below earth. Lava is expelled from earth. #2 Intermediate State: Sediment Broken rock fragments from the process of Weathering. Processes (There are 3!) 1. Melting and Cooling (Hardening) 2. Heat/pressure (Below Earth) Processes 3. Weathering, Eroding, Depositing, Compaction, Cementation (WEDCC) – Breaking apart of rocks into sediment fragments, and then transporting them to another location, where they settle. – Compaction: weight of overlying sediments causes pressure pushing sediments together – Cementation: minerals dissolved in water are transported and left behind to cement sediments together Do Now! Count off by 8 and get into groups. Try to arrange the rock cycle with the pieces given. Take out a new blank page and put your name at the top… Answer these questions… – 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?
