"Weathering and Erosion"
Bellwork:
•1) Something that affects how much a rock erodes is…
•2) Two ways that erosion transports weathered materials are __________ and _____________.
•3) The youngest rocks are found at the ____________ of a rock column.
- Review what we've learned about sand and erosion
- Introduce vocabulary: weathering vs. erosion
•Erosion helps wear down rocks but it only happens by moving them (wind, water, ice, gravity)
•Weathering breaks down rocks into smaller pieces (can be caused by chemicals and physical forces)
- View "Weathering and Erosion" video and complete the film questions on workbook pages 61 and 63

2) Igneous and sedimentary rock can change into ________________ rock.
3) _______________ rock is found in layers.
- Review the 3 types of rock: igneous, sedimentary, metamorphic
- Rock cycle simulation: use crayon shavings to create sediments, use pressure to create sedimentary rocks, melt the sedimentary rock to make magma for igneous rock, and use heat and pressure to create metamorphic rock
Notes:
- A) Igneous rock:
Lava cools and hardens into igneous rock
Ex: Basalt, pumice, and granite
- B) Sedimentary rock:
Sediments (broken bits of rock, dead plants and animals, chemicals) pile up, and the pressure smooshes them into rock layers
- C) Metamorphic rock:
Formed by heat and pressure
Rocks underground are squeezed and heated enough to change into metamorphic rocks
