Grab a Book!!!!!!!!!!!!! Warm Up: Draw a rock cycle diagram include the following terms: Intrusive igneous rock, extrusive igneous rock, metamorphic rock, sedimentary rock, melting, heat and pressure, weathering and erosion, uplifting. Quiz Monday! Classify rocks Density Mineral/Rock metamorphism rock cycle
Fault modeling What is the difference the Styrofoam moved in the 2 trials? Move the Styrofoam pieces so that they slide sideways, Draw picture of what happens with arrows showing dir. of force. Part C Make a color copy of the cross section diagram on page U42. What evidence suggests that rock layers were deformed by forces within the earth? Were the forces produced by pushing forces, pulling forces, or sideways forces?
Guided Reading Worksheet pages U43-U47 Get to #12 get 2 more tix What is a Fault? Fault: a fracture surface along which rocks slip. The forces are within the earth! What are the 3 type of forces? Tension Forces-Pull blocks apart Compression Forces: Pushing blocks together Shear forces: push blocks opposite directions What are the 4 type of faults Normal faults Reverse faults Thrust faults Strike slip faults Folds: Synclines & Anticlines
Exit Song (Slip) Rock Cycle Song Sedimentary rock Has been formed in layers Often found near water sources With fossils from decayers Then there’s igneous rock Here since Earth was born Molten Lava, cooled and hardened That’s how it is formed These two types of rocks Can also be transformed With pressure, heat and chemicals Metamorphic they’ll become
