Earth's surface (the LANDSCAPE) is constantly changing as a result of UPLIFT, WEATHERING, EROSION, and DEPOSITION. We've already covered all of these topics to some extent, but Unit 4 will cover them in a bit more detail.

There are 6 basic topics that will be covered in this unit

Topic 4A: River systems and drainage basins

By the end of topic 4A, you should

• be able to identify a drainage basin/watershed
• recognize common drainage/river system patterns
• recognize stream gradient profiles
• review how deposition will be controlled along the stream gradient profile
• be able to determine (once again) the sediment type that will be transported at various stream velocities
• recognize (once again) sediment depositional patterns associated with streams -- sorted and layered
  

Topic 4B: Glaciers

By the end of topic 4B, you should:

• know the difference between continental and alpine/mountain/valley glaciers.
• be able to describe how different proportions of accumulation and melting (ablation) will control the size and extent of the glacier.
• know that glacial ice is always flowing downhill
  
• recognize the common small scale evidence left behind by glaciation:
• • striations, erratics, polished bedrock, etc
• identify the large scale erosional and depositional remains from a glacier
• • erosional: aretes, horns, tarns, etc
  • depositional: drumlins, kettle lakes, eskers, terminal and recessional moraines
• recognize the sediment depositional patterns associated with glacial deposits (unsorted and un-layered)
  

Topic 4C: Groundwater

By the end of topic 4C, you should know:

• Porosity
• Permeability
  
• Capillary Action
  

Topic 4D: Mass Wasting

By the end of topic 4D, you should know:

• demonstrate how gravity influences mass wasting.
• identify various forms of mass wasting
• • landslides, mudslides/mudflows, creep, slump, etc
    

Topic 4E: Wind/Deserts/Beaches

By the end of topic 4E, you should know:

• the differences between leeward and windward sides of sand dunes.
• know how wind influences sand dune migration
• identify the likely direction of long shore drift on beaches
  

Topic 4F: Soil

By the end of topic 4F, you should know:

• the difference between residual and transported soils
• 
  
•
