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

3. WarmUp ( )
Explain the difference between weathering and erosion.
Weathering: the breaking of rock by wind, rain, ice, etc.
Erosion: the movement or carrying of sediments

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
3 Deposition 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 Lithification Deposited 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.
