Aim & Learning Target Aim: Learning Target: How do we classify and evaluate metamorphic rocks? Learning Target: I CAN explain how metamorphic rocks are formed and on what basis they are classified
Do Now Open your Reference Tables to the Rock Cycle. Looking at the Metamorphic Rock Chart try to fill in the chart below
Do Now Check: Read the following statement: Your family goes hiking up Bear Mountain. On your way up the mountain you stop and pick up 3 rocks. You tell your family that they are all metamorphic rocks based on the layers and stripping that they show. Thumbs up you agree Thumbs down you disagree
Metamorphic Rock When any type of rock (sedimentary, metamorphic, igneous) undergoes METAMORPHISM (subjected to heat and pressure) forms a metamorphic rock.
Two types of metamorphism Contact and Regional (heat) Magma/lava will hit into the rock, causing it to change into a metamorphic rock Regional (pressure) Layers of rock on top cause pressure to build up metamorphism
Characteristics of metamorphic rock Foliation & Banding wavy bands of dark and light minerals Ex – Gneiss Mineral Alignment – interlocking crystals ----- Meeting Notes (12/13/12 14:18) ----- cheryle is the best rock' Hey Ms c :-D
What pg of the ref table can you find the Scheme for Metamorphic Rock identification? Page 7. What does it tell us about metamorphic rocks? How does marble form?
For the classwork questions you have to use the rock cycle. A lot of these questions come straight from the Regents. For Tonight’s HW, use the classification schemes. HW is 1-13
