Study Notes
Unit 5: Where Does All The Water Go?
- Unit 4 materials should be put aside for the midterm on Feb 5, 2025.
Today's Objective: What is a Landscape Region?
- A landscape region is a section of Earth's surface where landforms share a common origin.
Topography
- Topography displays the shape of the land, highlighting different landscape regions.
Relief
- Relief is the change in elevation.
Major Landscape Regions
- Three major landscape regions are plains, plateaus, and mountains.
- These are categorized by bedrock and elevation.
Mountains
- Mountains have the greatest relief.
- They are characterized by peaks and valleys.
- Bedrock is not horizontal.
- They are typically made up of metamorphic rock.
Plateaus
-
Plateaus have medium relief.
-
They have several stream valleys.
-
Bedrock is flat.
-
They are mostly made of sedimentary rock.
-
Example Differences:
- Catskills: Dissected plateau, sedimentary bedrock
- Adirondacks: True mountains, metamorphic bedrock
Plains
- Plains have little relief.
- They have a low elevation.
- They are flat.
Climate Influence on Landscapes
- Precipitation affects measurable landscape characteristics.
- Wet climates lead to thick, rich soils and smooth, rounded landscapes.
- Dry climates result in thin soils, little humus, and sharp angles/steep slopes.
Factors Affecting Landscapes
- Softer rock erodes more quickly than harder rock.
- Durable rock forms higher portions of landscapes such as plateaus, mountains, and cliffs.
Drainage Patterns
- Water flow patterns depend on bedrock structure.
- Drainage patterns are determined by how small streams (tributaries) join larger streams.
Drainage Pattern Examples
- Radial: Water flows in all directions from mountainous areas.
- Dendritic (branching): Water branches together, typical of flat plains.
- Trellis (rectangular): Water flows in rectangular patterns, common in plateaus with folded or faulted bedrock.
- Annular: Water flows in circular patterns around an igneous intrusion.
Drainage Basin (Watershed)
- A drainage basin is the area where water flows off a landscape region into a body of water (ocean or stream).
