  1. Rock Cycle Unit

  2. WarmUp (2-25-13) • How are rocks made? • Igneous Rock is formed from cooled lava • Sedimentary Rock forms from eroded rock layers • Metamorphic Rock forms from changed sedimentary rock Agenda: WarmUp Lava Pillows How It’s Made Lottery 5. Bill Nye 6. Poster

  3. WarmUp (2-26-13) • Explain the difference between weathering and erosion. • Weathering: the breaking of rock by wind, rain, ice, etc. • Erosion: the movement or carrying of sediments Agenda: WarmUp How It’s Made Bill Nye Finish Poster

  4. Rock Cycle Poster 2.Weathing of Igneous Rock: Rain and wind breaks the rock: This called WEATHERING Erosion: The removal of rock is called erosion: Water erodes through carrying the rock 3Deposition Broken rocks run to ocean as SEDIMENT and are dropped when they become too heavy for wind or water Igneous Rock 1.Crystallizationof Igneous Rock: Igneous rock is formed from cooled magma. 5 Metamorphism :Sedimentary rocks are squeezed by heat and pressure and are changed into completely new rock… these are called METAMORPHIC ROCKS 5 Melting back into Magma: Metamorphic rock is pushed down and is melted by high heat and volcanism… this magma may become igneous some day. Sedimentary Rock Metamorphic Rock 4 Compaction and LithificationDeposited rocks are squeezed together and cemented into SEDIMENTARY rock through LITHIFICATION Subduction: Sedimentary rock is carried down below other plates because ocean plates are heavier. *** Lithos-= Stone -Fication=To make into
