Agents of Erosion TAG Earth Science

1. Agents of ErosionTAG Earth Science A Webquest

2. Write this in your agenda • Homework for tonight: Complete question strip #4 • Work on your natural wonders /erosion project • Study your flash cards • Tomorrow in class we will finish the foldable for section 4. You do not have to work on it tonight.

3. IMPORTANT DATES • Our test over Chapter 12 will be on Wednesday, 11/20. Make sure to study your flash cards and questions strips and notes nightly. This will help you prepare for it. • Natural Wonders/Erosion Project is due on Thursday, 11/21. Make sure that you are working on this every night. Do not wait until the last minute.

4. announcement • Your test will contain a few questions from topics we have covered in the past. You will need to review these concepts in your notebook: • The water cycle • Weathering vs. erosion vs. deposition: what is the difference? • What are the 3 types of rocks and how are they formed? • The rock cycle- intrusive rocks vs. extrusive igneous rocks • What is “topsoil”? • In the metric system, what is the basic unit of length? Mass? Volume? • Ice wedging • (I will post this list again on Edmodo).

5. Directions for webquest • Follow the directions for each slide. Answer the questions in complete sentences in your composition notebook on P. 81. (You can make an 81a, 81b… if necessary) • Each slide of this Power Point will have links to resources on the internet about weathering, erosion, and deposition. Some slides have questions to answer, and some do not. Read the information on the websites carefully! Remember, your goal here is tolearn, not to fly though the material on the websites and see how fast you can answer the questions. 

6. Again… this is important • Read the information on the websites carefully! Remember, your goal here is tolearn, not to fly though the material on the websites and see how fast you can answer the questions. 

7. Standards covered in this webquest Standards covered in this WebQuest: • S6E3. Students will recognize the significant role of water in earth processes. • S6E5. Students will investigate the scientific view of how the earth’s surface is formed. • d. Describe processes that change rocks and the surface of the earth. • f. Explain the effects of physical processes (plate tectonics, erosion, deposition, volcanic eruption, gravity) on geological features including oceans (composition, currents, and tides). • i. Explain the effects of human activity on the erosion of the earth’s surface. • j. Describe methods for conserving natural resources such as water, soil, and air.

8. National Geographic’s Photo Gallery of Erosion and Weathering • Click on the link below to view National Geographic’s Photo Gallery of Erosion and Weathering. • You will need to click on the “next” picture after each picture. Read each caption carefully. (No questions to answer for this, just enjoy the beautiful pictures! ) • http://science.nationalgeographic.com/science/photos/weathering-erosion-gallery.html

9. Visit the website below. You will start on the slide below and click through several slides. Carefully read the descriptions and look at the pictures. (There are no questions to answer for this. Just read carefully and learn.) http://www.kidsgeo.com/geology-for-kids/0060-weathering.php

10. 1. What is the difference between weathering and erosion? Read the information on the two websites below before you compose your answer. Give a thorough explanation! • http://www.kidsgeo.com/geology-for-kids/0060-weathering.php (Note: You just visited this one. Read this one slide again.) • http://www.nature.nps.gov/geology//usgsnps/misc/gweaero.html

11. Effects of erosion and depositon • 2. What are the effects of weathering, erosion, and deposition on the surface of the Earth? (In other words, name the ways that weathering and erosion change the surface of the earth.) Make a bulleted list. (You will need a lot of room for your answer! You will keep adding on to your answer as you go through this webquest.) • View the links and list as many ways possible that weathering, erosion, and deposition affect the surface of the Earth. As you go though this Power Point today and visit different websites, you may add to your list. Below are links to get you started. • http://www.geography4kids.com/files/land_erosion.html • http://magma.nationalgeographic.com/ngexplorer/0610/articles/mainarticle.html

12. How does weathering and erosion affect man? • Carefully read the website below and answer the following questions: Answer the questions in complete sentences in your composition notebook. 3. What are landslides? What are other names for landslides? 4. Where can landslides occur? 5. What is the most common type of slide? 6. Which areas are generally prone to landslides? 7. Which areas are generally safe from landslides? 8. Name 5 features that might be noticed before landslides. (Warning signs) • http://www.ussartf.org/landslides.htm#top

13. Urbanization and erosion • 9. Read the short website below about how construction (building homes and buildings) can cause erosion without proper erosion control techniques. Answer this question: How can urbanization cause erosion? • ur·ban·i·za·tion- to make (especially a predominantly rural area or country) more industrialized and urban; building/construction on a rural area Used in a sentence: Urbanization has led to more air pollution and increasing childhood asthma. • http://ga.water.usgs.gov/edu/urbansed.html

14. How can erosion be prevented? • 10. How can humans prevent the negative effects of weathering, erosion, and deposition on the surface of the Earth? Click on the links to read about how man can prevent erosion: Note: for the link below, be sure to click on the “Instructions” link! • http://www.environment.ualberta.ca/SoilPosters/wind.cfm • http://www.landscapeplanet.com/maintenance-1-soil-erosion-prevention.htm

15. Cool websites about erosion • The rest of the slides of this webquest are filled with wonderful information. There are no questions over the information, but you are required to participate in viewing the websites. • All of the websites support what we have learned in class. They provide a great visual of the information.

16. glaciers • Watch the video below about Tracking the Byrd Glacier. • http://science360.gov/obj/video/0d0b75f4-1376-449c-a8e6-6550789c6a59/tracking-glacier

17. Wind erosion Click on the link below to watch videos about wind erosion. • http://www.weru.ksu.edu/vids/

18. How caves form • Watch the animation to see how caves form. Be sure to click on the “Forward” button to advance the animation. http://www.teachersdomain.org/asset/ess05_int_caveform-fla/

19. The grand canyon What do you get if you mix erosion, volcanoes, a hot and dry climate and the Colorado River? If you’re really lucky and have a lot of time – at least a million years – you get the Grand Canyon. Located in Arizona, this huge hole in the ground shows the Earth – right down to the bone. Click on the link below to read more about it. Be sure to watch the video about the creation of the Grand Canyon! • http://www.kidsgeo.com/geology-for-kids/0078B-grand-canyon.php

20. The grand canyon • Click on the link below for a picture of the Grand Canyon from space. You will need to scroll down for the picture. • http://www.kidsgeo.com/geology-for-kids/0081-erosion-experiment.php

21. Additional resources • Below is an excellent website put together by a college professor about Erosion. • Please navigate through it and add any additional information you need to your questions. • The section about how Providence Canyon is Georgia was formed is especially interesting. • http://facstaff.gpc.edu/~pgore/Earth&Space/GPS/erosion.html

22. Textbook e-Activities • When you are done, go to the online textbook • Http://my.hrw.com • User name: 3942 • Password: n9j8s • Select on of the dropdown menu: Chapter 12: Agents of Erosion and Deposition • Go to the eActivities tab and watch the computer animations for the chapter. This is a great review!

23. brainpops • To review concepts we have learned in the past, please view these Brainpops and complete the review questions: • The Water Cycle • Rock Cycle • Types of Rocks • Soil
