Presentation Transcript

  1. Earth ScienceErosion/Deposition

  2. Agents of Erosion • Moving Water (Rivers & Runoff) • Moving Ice • Wind • Mass Movement • Waves

  3. Erosion/Deposition: Moving Water (Rivers) • D.E.Q. How does Moving Water (Rivers) change the surface?

  4. Erosion/Deposition: Moving Water (Rivers) • Greater slope will: (Determined by terrain) • Increase the force of gravity, and in return: • The V-shaped river valley will be deeper • Have faster moving water • Carry more sediment (cause more erosion) • Have a narrower river • Take a straighter course

  5. Erosion/Deposition: Moving Water (Rivers) • Greater slope Farmington River

  6. Erosion/Deposition: Moving Water (Rivers) • Greater slope

  7. Erosion/Deposition: Moving Water (Rivers) • Lesser slope will: (Determined by terrain) • Decrease the force of gravity, and in return: • The V-shaped river valley will be shallow • The water will slow down • The river becomes wider • The sediments will start to settle (DEPOSITION) • The river’s course will meander (bend and loop) • Delta will form where river exits into a larger body of water

  8. Erosion/Deposition: Moving Water (Rivers) • Lesser slope Meander Farm River

  9. Erosion/Deposition: Moving Water (Rivers) • Lower Slope Farm River Delta

  10. Erosion/Deposition: Moving Water (Rivers) • Lesser Slope • Farm River
