One way that the balance of existing ecosystems is changed is with the introduction of non-native species or invasive species. Over the years non-native species both plant and animalhave been introduced either deliberately or by accident into the Great Lakes and Lake Erie waters and area. Name two flora invasive species that have invaded this area? How did they arrive in the area? Explain one way that non-native species invade the lakes. Name three non-native species and explain how have they affected the balance of the great lakes? ecosystem?Is there one species that is not here yet but that is seen as a problem for the future? What are environmentalists trying to do to keep this species out of the Great Lakes?

There is discussion among scientists concerning the theory of plate tectonics.The theory of plate tectonics is important for scientists to study the Earth?s history and to learn about the Earth?s surface major relief surfaces and the ocean?s floor. What is the theory of plate tectonics and when did it evolved? What does the word plate and word tectonics describe?Why is the theory of plate tectonics important for Earth?s history? Describe the types of plate boundaries. Give examples and location for each type. Where are the seven major plates located?(You may need to provide a copy of a map with the explanation} How did Alfred Wegener play a major role in the evolution of the plate tectonic theory? What is Pangaea?How are the movements of plates related to Pangaea? Define and describe the Wilson Cycle.What is the relationship to plate tectonics? What is the relationship between earthquakes and volcanoes and plate tectonics? How has the theory of plate tectonics helped developed the exploration of the ocean especially the ocean floor?

It provides us with heat and light.There is much we can learn about the sun that will provide us with a great understanding and appreciation for it. ( 40 points) How old is the Sun?How is the age estimated?How does it compare to other stars (suns) found in the universe?How is its energy generated?How much longer is it estimated to continue to generate energy for the earth? It is said that the Sun will burn for billions of years. What is incorrect about that statement? What is a sunspot?What kinds of problems can they cause?How many sunspots occur in a year?Do these cycle on a regular basis?What is the difference between Coronal Mass Ejection vs a Solar Flare. When we say that we see sunspots on the Sun?s surface does this mean that there is actually a surface on the Sun? What is a solar storm? How do solar storms affect (sunspots coronal mass ejections and flares) us on earth?What causes these effects?Can such storms impact the electrical grid here on earth?Has this ever happened in the past?Is anything else affected? What is a solar eclipse?What happens during a solar eclipse?When does a solar eclipse take place? What isSOHO the Solar and Heliospheric Observatory and what have scientists learned about the Sun? What type of rays does the Sun emit? What should one do to protect eyes and skin from the Sun?s rays?(40 points) Hints http://science.howstuffworks.com/sun.htm http://www.swpc.noaa.gov/primer/primer.html http://www.crh.noaa.gov/fsd/astro/sunspots.php http://www.exploratorium.edu/sunspots/ http://www.solarstorms.org/ http://www.spaceweathercenter.org/ http://www.absoluteastronomy.com/topics/Solar_eclipse www.nasa.gov http://helios.gsfc.nasa.gov/magnet.html http://missionscience.nasa.gov/sun
