  1. Weathering & Erosion

  2. Blue foldable • Outside: Weathering • Inside: The break down of rock into smaller and smaller pieces • Forms sediment • Happens to rocks that are not moving

  3. Chemical Mechanical or physical Blue: Two Flaps

  4. Blue flap: Mechanical or Physical Weathering • Inside: • Breakdown of rock by physical means • Just changes the look of the rock

  5. Blue flap: Chemical Weathering • Inside: • Breakdown of rock by chemical means • Forms a new substance

  6. Green foldable: • Outside: Agents of Mechanical Weathering • Inside on flaps: • Ice • Wind • Water • Gravity • Plants • Animals

  7. On inside of Agents of weathering foldable • Abrasion: rocks grind against each other and wear away their surface • Rocks rub together in streams • Chalk on chalkboard

  8. Ice: • inside: Ice wedging: water freezes in cracks. When it expands, the crack gets bigger. • Wind: • Inside: wind forces rocks into each other • Water: • Inside: rivers and streams roll rocks into each other

  9. Gravity: • Inside: gravity pulls rocks down into each other • Ex: rock slide • Plants: • Inside: roots break apart rock • Animals: • Inside: Animals that dig break apart rocks

  10. Pink foldable: • Outside: Agents of Chemical Weathering • Inside on flaps: • Water • Acid rain • Lichens • Air

  11. Water: • Inside: water can eat away certain types of rocks & minerals • Acid rain: • Inside: acids in rain causes rocks to change • Lichens: • Inside: plants that give off acid & eat away rocks • Air: • Inside: air causes oxidation • Oxidation: oxygen in air react with another element to form an oxide • Creates rust

  12. Gold foldable • Outside: Differential weathering • Inside: Process where softer, less weather resistant rocks wears away leaving harder rock behind.

  13. Yellow Foldable • Outside: 4 things that affect the rate of weathering • Inside on flaps: • Hardness of rock • Surface area exposed • Climate • Elevation

  14. Hardness of rock: • Inside: harder rocks weather slower than soft rocks • Surface area exposed: • Inside: smaller rocks weather faster than larger rocks • Climate: • Inside: oxidation occurs more in warm, wet climates • Elevation: • Inside: rocks at higher elevations are exposed to more water and wind -> more weathering • Steeper mountains cause more weathering

  15. Purple Foldable: • Outside on 1st flap: Erosion • Inside: the transport of sediments from one place to another • Outside on 2nd flap: Deposition -Inside: when sediments are dropped off

  16. White Foldable: • Outside: Agents of Erosion & Deposition • On flaps: • Water • Wind • Ice • Gravity

  17. Water: Inside: moves sand &small rocks and deposits them in a new location Wind:Inside: moves sand and small rocks and deposits them in new locations Ice: Inside: Ice moves sand and all kinds of rocks to new locations Gravity:Inside: sediments move downhill

  18. Salmon Foldable: • Outside: Landforms created by weathering, erosion, & depositionInside labels: - Green = wind - Pink = Gravity - Yellow = Ice - Blue = Waves

  19. Landforms made by wind • Sand Dunes

  20. Landforms made by Gravity: rock falls, landslides

  21. Landforms made by Ice: Glue in whole white picture

  22. Landforms created by waves • Sea stack Sea arch

  23. Beaches • Sandbars • Barrier spit

  24. Sea cliff • Wave cut terrace

  25. Headlands
