Procedure
Complete each task below in order. Record your answers to each question on the worksheet provided:
1. First, you will need to understand how the surface of the earth is changed through weathering and erosion. Watch this studyjams video and complete the quiz after watching. Click on the "play video" button first. When the video is finished, click on the "test yourself" button to take the quiz. If you miss more than one question, watch the video again before moving on. What is the difference between weathering and erosion? How do weathering and erosion work together to change the environment?
2. To test your knowledge of how weathering and erosion work together to change the surface of the earth, play this interactive game.
3. Now that you have a better understanding of how weathering and erosion change the surface of the earth, we need to look at how erosion affects the coastline. Read this short article and answer these questions: What causes beach erosion? Why is beach erosion a problem?
4. To see examples of beach erosion in action, watch this video clip. While you are watching, what specific example is provided of erosion in North Carolina?
5. To understand how coastal erosion is prevented, use visit these four websites. Each website lists methods used for preventing erosion. Write down at least two methods from each website that you visit.
C) Coastal Geological Processes On this site, click "launch". Next, click "human modifications" in the bottom right corner. From there, click on each of the three "soft structures" and each of the four "hard structures" to view a photograph and description of each prevention method.
D) Britannica: Groin, Breakwater, Jetty
Which method(s) do you think are best for preventing beach erosion?
Watch this video to see examples of the erosion prevention methods.
6. To see coastal erosion and the moving and shifting of sand over the years, use this interactive site to see Google photos over time. You can click on the names of the different inlets at the bottom of the page to look at different places and how they have changed. Seeing how much the coastline of North Carolina changes from year to year, do you think that trying to stop the erosion is worth it?
