Plate Tectonics Virtual lab (replacement)
Goals of this lab:
-to learn about types of Plate Boundaries
-to learn about Plate Boundary Interactions
-to familiarize yourself with the Plate Tectonic Map of the World
-to understand and familiarize yourself with past Plate Movement and the supercontinent Pangea
-to understand the Hot Spots of Hawaii and Yellowstone
Make sure you respond to EACH question with at least TWO FULL SENTENCES!!!!!
Part 1. Types of Plate Boundaries
There are 3 types of plate boundaries and a fourth called a “plate boundary zone” in which the type of plate boundary is not clearly defined. Go to the website: http://pubs.usgs.gov/publications/text/understanding.html
learn about the three types of plate boundaries and answer the questions below.
1. What are the three types of plate boundaries?
2. What directions do the plates move relative to one another in a divergent plate boundary?
3. What is a spreading center and what is made at one?
4. Name one spreading center (or divergent plate boundary).
5. What are the three types of convergent plate boundaries?
6. What two kinds of crust are involved in a subduction zone?
7. What type of convergent boundary are the Himalaya Mountains formed by?
8. What happens along a transform plate boundary?
9. Name a famous transform fault in western North America.
10. Which plates are sliding past each other along the San Andreas Fault?
Part 2. Plate Boundary Interactions
Now, go to https://youtu.be/ZzvDlP6xd9o
and watch the short video clip on Sea Floor Spreading.
12. What is sea floor spreading? 13. If sea floor spreading is happening, why isn’t the earth “growing”?
Now, go to http://www.classzone.com/books/earth_science/terc/content/visualizations/es0804/
es0804page01.cfm?chapter_no=08
to learn more about plate boundary interactions.
14. Watch EACH of the 3 animations—for EACH animation, draw a simple sketch of the plates and show HOW they are each moving and
explain one event/structure that happens or is formed as a result of that type of plate boundary interaction. Part 3. Plate Tectonic Maps Now go to http://denali.gsfc.nasa.gov/research/lowman/Lowman_map1_lg.jpg
and you will see a plate tectonic map of the world. Use the magnifying glass icon to zoom in on the image. Now you can use the scroll bars on the side and bottom to maneuver around the map.
15. Using the key at the bottom of the map, what is happening in Idaho, tectonically speaking?
16. Scroll over to Asia and locate the Java Trench. This is where the Indian Plate and Eurasian Plate interact. What kind of plate interaction occurs here, that was responsible for the December 26, 2004 tsunami?
Now open http://www.classzone.com/books/earth_science/terc/content/visualizations/es0807/
es0807page01.cfm?chapter_no=08
and watch the animation. Pick two areas where two or more of Earth's plates
would overlap in the future. Imagine how Earth's actual plates might respond to the projected plate motion.
17. Predict one event/thing that might happen due to this projected plate motion. Make sure to state WHERE you are looking!
Now go to http://www.classzone.com/books/earth_science/terc/content/visualizations/es0806/
es0806page01.cfm?chapter_no=08
Watch the animation on how the plates looked around 150 million years ago, when all the continents were together forming the “supercontinent” Pangea, and how the plates moved through time to their present configuration.
18. What continents did North America used to be attached to during Pangea time?
Part 4. Hot Spots
Now, go to the website: http://pubs.usgs.gov/publications/text/hotspots.html
to read and learn about hot spots. 19. What are hotspots and how do they influence how Earth looks?
