ASTM101 Unit 9 HW All homework assignments assume that you have read and have access to the lecture notes. Watch this video on differentiation and then answer the two questions below. 1. What do you notice about how dense each layer of the Earth is as you go from the crust to the core? 2. Why does a trend in density exist? If you want to look at pictures of some of the rocks and minerals that make up the Earth then check out the rock pictures and mineral pictures on Blackboard. Go to the British Geological Survey: https://www.bgs.ac.uk/discoveringGeology/hazards/earthquakes/whatIs.html https://www.bgs.ac.uk/discovering-geology/earth-hazards/earthquakes/how-are-earthquakes-detected/ 3. What causes an earthquake? 4. Describe an S wave. 5. Describe a P wave. Read about how to read a seismograph: http://www.geo.mtu.edu/UPSeis/reading.html 6. Are S or P waves bigger (greater amplitude) on a seismograph? Watch this video on how S and P waves are used to find the epicenter of an Earthquake: https://youtu.be/694yaY2ylTg 7. What is found from the seismograph? 8. In your own words, how is the epicenter of an Earthquake found? Go to the Plate tectonics 1 link. Watch the movie demonstrating the movement of Earth’s crust. Go to the Plate tectonics 2 link. Read about plate tectonic theory. 9. The first link at the bottom of the page is labeled sea floor spread. What type of plate boundary is this? 10. Click on the sea floor spread link. What does magma do at that plate boundary? 11. Click on the Continental Slide link. What type of plate boundary is this? 12. What geological feature is created by this type of plate interaction? 13. Click on the Continental Crush link. What type of plate boundary is this? 14. What geological feature is created by this type of plate interaction? 15. Click on the "Slippin' and a Slidin” link. What type of plate boundary is this? 16. What occurs at this type of plate boundary and why? 17. Why is your answer for question 12 different than your answer to question14? Go to the Aurora Borealis Explained link. 18. Where do the charged particles that interact with Earth’s magnetic field come from? 19. Why do the aurora occur at the poles and not the equator? 20. What process causes the lights that we see to occur? 21. What color light do the oxygen molecules emit? 22. What color light do the nitrogen molecules emit? 23. View images of the surface of Mercury, Venus, and Mars by using the links provided. Compare and Contrast the surfaces of these planets. Please do not forget about the concept of false color images that we learned about during Week 1. There are several maps included on the linked pages where you would want to look for a legend.
