Erosion in the Outer Banks
http://www.lib.unc.edu/dc/ncmaps/erosion_k12.html
A lesson plan for grades 9–12 Science
In this environmental science lesson, students examine different perspectives on erosion in the Outer Banks over the past century by implementing research and map comparisons between Google Earth and early 20th-century coastal maps. This lesson assumes a basic knowledge of erosion terms as well as latitudinal and longitudinal direction.

Grade 9–12 — Earth/Environmental Science
- Goal 2: The learner will build an understanding of lithospheric materials, tectonic processes, and the human and environmental impacts of natural and human-induced changes in the lithosphere.
- Objective 2.05: Create and interpret topographic, soil and geologic maps using scale and legends.
- Goal 4: The learner will build an understanding of the hydrosphere and its interactions and influences on the lithosphere, the atmosphere, and environmental quality.
- Objective 4.01: Evaluate erosion and depositional processes:
- Formation of stream channels with respect to the work being done by the stream (i.e. down-cutting, lateral erosion, and transportation).
- Nature and characteristics of sediments.
- Effects on water quality.
- Effect of human choices on the rate of erosion.
- Objective 4.03: Analyze the mechanisms that produce the various types of shorelines and their resultant landforms:
- Nature of underlying geology.
- Long and short term sea-level history.
- Formation and breaking of waves on adjacent topography.
- Human impact.
- Objective 4.05: Investigate and analyze environmental issues and solutions for North Carolina's river basins, wetlands, and tidal environments:
- Water quality.
- Shoreline changes.
- Habitat preservation.
- Objective 4.01: Evaluate erosion and depositional processes:
