Presentation Transcript

  1. Gradation

  2. Outcome C describe the features and processes associated with weathering and mass wasting

  3. Outcome C Weathering http://www.youtube.com/watch?v=lyysL02ZvQ8 Physical Weathering- Chemical Weathering-

  4. Physical Weathering-Outcome C-1 Frost Shatter

  5. Formative Task 1 Read Page 38.. Draw a labelled illustration of each type of Physical Weathering.

  6. Outcome C-2-Chemical Weathering Involves the decay of rock so that the chemical composition of the rock is changed...

  7. Processes.. Solution--- As rain droplets pass through the atmosphere they absorb CO2 and form a mild acid called Carbonic acid.. This acid rain will dissolve rock like limestone...

  8. Solution

  9. Hydrolysis Carbonic acid works on minerals called silicates. Ions of water replace ions of silicate and the dissolved minerals are carried away in the water.. Eg. Water-- Through coffee grounds..

  10. Oxidation Oxygen dissoved in water can change iron into iron oxide. As water comes in contact with the iron oxide, it disolves it and carries it away... A red rust stain on rocks is an indication that oxidation is taking place..

  11. vIDEO-- Chemical Weathering.. http://www.youtube.com/watch?v=P8oWj3PVK9E

  12. Weathering Vs. Erosion Remember that weathering is the breakup of rock... Erosion means both breakup and transportation..

  13. Formative Task 1 Draw out an label examples of each in your notebook.. Write out the steps and colour as well...

  14. Identify and Describe Process Chemical vs Physical Type of Chemical or Physical Process - Three Steps

  15. Outcome C-3- describe features and processes associated with mass wasting

  16. Causes of Mass Wasting.. Natural Causes: 1.Adding Water-expands soil and reduces stability. 2. Freeze/thaw in winter reduces soil stability.. Human Cause 1. Logging- Destabalizes slopes. 2.Urbanization

  17. Solutions: From page 40(Geo 12 workkbook)identify 8 techniques used to stabalize slopes so that Mass Wasting does not occur...

  18. Types and Processes of Mass Wasting From Pg 41 (geo 12 Workbook) Identify and describe the process for each of the seven types of Mass Wasting... Use a diagram to demonstrate your understanding of each...

  19. Rubric for Diagram/Process Exp.. 4- Includes detailed- 7 labelled drawings, includes at least a 5 step detailed process for each. 3-Includes detailed at least 5 labelled drawing, includes at least a 5 step detailed process 2-Includes a detailed of 4 labelled drawing, includes at least a 4 step detailed process 1-Includes detailed all 2labelled drawing, includes at least a 5 step detailed process

  20. Outcome C Identify and describe processes associated with..... running water (e.g., stages of fluvial development, methods of sediment transport, abrasion, hydraulic action, vertical erosion, lateral erosion, headward erosion) – ground water (e.g., solution) – glaciation (e.g., plucking, abrasion) – wind (e.g., deflation, abrasion) – waves (e.g., longshore drift, abrasio

  21. identify the erosional and depositional features associated with – running water (e.g., meander, oxbow lake, levee, flood plain, delta, drainage pattern, alluvial fan, playa) – ground water and Karst topography (e.g., sink hole, stalactite, stalagmite, artesian well, aquifer) – glaciation (e.g., cirque, arête, horn, truncated spur, hanging valley, roche moutonnée, crag and tail, drumlin, kettle lake, moraine, tarn, esker) – wind (e.g., barchan, loess, mesa, butte, hamada) – waves (e.g., headland, stack, spit, bar, tombolo) i

  22. Outcome C-4 Identify/Describe Drainage Basins Using Googe Earth Find the following Locations and Identify the type of Drainage Patterns Mt Rainier Bella Colla B.C- river that flows beside the town. Fayettville North Carolina

  23. Dendritic Pattern

  24. Radial Pattern

  25. Trellis Pattern

  26. Outcome C 5- Identify Stages/Describe River Development Outcome C5

  27. Youthful

  28. Mature

  29. Old Age River

  30. River Stages- Identify-Google Earth Go to Mount Robson Visitor Centre- Find Picture nearby of Fraser River Headwaters.. Go to Mission B.C. find the Fraser River identify the river stage. Go to Hells Gate BC- Identify the River Stage Find at least 3 other rivers and identify the stage they are at...

  31. C-6 Identify/Describe 4 Erosional Processes of Rivers C-6 1. Hydraulic Action 2.Abrasion 3.Attrition 4. Collision Define each one-Draw a picture.

  32. C7.Identify/Describe Erosional/Transportation 1. Solution 2, Suspension 3. Saltation 4. Traction Define each one- Draw a picture..

  33. Google Earth Tours. You will create a google earth tour: You will need to identify the features and processes forming the featues of one of the following areas: 1. Pg 44- 46-Upland/Lowland Rivers Eg. Fraser 2.Pg. 49- 54- Alpine/Cont. Glaciation Eg Mount Robson. (Berg Lake) 3. Pg. 54-57 Coastal Landforms (Eg. Oregon Coast)

  34. Google Earth Tours 4. Pg. 58-60- Groundwater-- 5. Pg. 60-64 -Desert Landscapes..

  35. C-8 identify/Describe Formation of Upland/Lowland River Features- C8 Upland Process- Vertical Erosion dominates as gradients are steep. Features: Water Falls, Gorges,Canyons, Boulders, Potholes,.

  36. Lowland Features Process-river has reached an elevation close to sea level. Energy used is lateral not vertical. Features- Flood plains, meanders,undercuts,point bars, slip off slope,levees,dikes, oxbow lakes, river terraces,braided channels, river deltas.(arcuate delta,birds foot delta,and estuarine delta..

  37. C 9- Identify Features and Formation Process of Alpine Glaciers Process- Formation Accumulation, abalation,formation Erosion Actions(Processes) Plucking,Abrasion,Deposition,Till and Outwash

  38. C-9 Continued. Identify Erosional Feature and Describe Process Cirque,Tarn, Arete,Col,Horn,Striations,Ground Moraine,Lateral Moraine,Medial Moraine,Termianl Moraine, Pro Glacial Lake,Snout, Recessional Moraine, Esker, Truncated Spurs, Hanging Valleys, Crevasses, Icefall, Glacial Lakes,

  39. C-10 Identify Coastal Landforms and Formation Process Erosional Actions- Describe Waves, Wave Action, Wave Refraction, Coastal Erosion: Describe Corrosion,Corrasion,Attrition, Hydraulic Action, Undercutting,swash,backwash,longshore drift. Identify Features and Describe Formation of: caves,bay, headlands,tunnel,arch stacks,
