  3. HOW DOES RUNNING WATER SHAPE A LANDSCAPE? 1. Chemical Erosion: 2. Clastic Erosion:

  4. HOW DOES RUNNING WATER SHAPE A LANDSCAPE? 1. Chemical Erosion: Removal of Earth material at the molecular level. 2. Clastic Erosion:

  5. HOW DOES RUNNING WATER SHAPE A LANDSCAPE? 1. Chemical Erosion: Removal of Earth material at the molecular level. 2. Clastic Erosion: Erosion resulting from the force of running water playing over the surface of small pieces of rock.

  12. WHAT FACTORS CONTROL THE RATE OF CHEMICAL SOLUTION? 1. 2. 3.

  13. WHAT FACTORS CONTROL THE RATE OF CHEMICAL SOLUTION? 1. Level of dissolved substance already in solution. 2. 3.

  14. WHAT FACTORS CONTROL THE RATE OF CHEMICAL SOLUTION? 1. Level of dissolved substance already in solution. 2. Temperature. 3.

  15. WHAT FACTORS CONTROL THE RATE OF CHEMICAL SOLUTION? 1. Level of dissolved substance already in solution. 2. Temperature. 3. Surface area (degree of fracturing of rock).

  16. How does the level of dissolved substance already in solution control the rate of solution? In a finite volume of water there is a finite capacity to break molecules apart.

  17. How does the level of dissolved substance already in solution control the rate of solution? In a finite volume of water there is a finite capacity to break molecules apart.

  18. How does the level of dissolved substance already in solution control the rate of solution? As total dissolved approaches saturation level, rate of solution declines.

  19. How does the level of dissolved substance already in solution control the rate of solution? As total dissolved approaches saturation level, rate of solution declines.

  20. How does the temperature control the rate of solution? The process of solution is a chemical reaction, and most reactions go faster in the presence of more energy (temperature). Temperature also controls the maximum saturation level.

  21. Change Rate:

  22. Change Maximum Saturation :

  23. Change Both:

  24. How does the does the degree of fracturing influence solution? Cubic rock (4mx4mx4m) = 64m3 surrounded by water. Solution only occurs at the interface between the rock and the water.

  25. How does the does the degree of fracturing influence solution? Cubic rock (4mx4mx4m) = 64m3 surrounded by water. Solution only occurs at the interface between the rock and the water. Surface area of interface: 6 Faces to cube, each has surface area of (4m x 4m = 16 m2), 6 * 16 = 96 m2

  26. Cubic rock (4mx4mx4m) = 64m3 surrounded by water. Cut rock in half in each dimension -solution occurs at the interface between the rock and the water. Surface area of interface: 8 Cubes each with 6 Faces to cube, each has surface area of (2m x 2m = 4m2), 48 * 4 = 192 m2

  27. Cubic rock (4mx4mx4m) = 64m3 surrounded by water. Cut rock again in each dimension -solution occurs at the interface between the rock and the water. Surface area of interface: 64 Cubes each with 6 Faces to cube, each has surface area of (1m x 1m = 1m2), 64 * 6 = 384 m2
