1. The following is an image of an ocean basin in profile view. The dashed line represents Sea Level. The stars show where volcanic activity is present (there is NO volcanic activity in any other region). (8 points) a. Draw a solid line at each plate boundary on the image below. Be very careful, no partial credit will be given for vague boundary lines. b. How many tectonic plates are present? _________________________________________ c. Label an area on the graph where you would be very likely to find andesite. d. What do we call the feature labeled “x” in the image? __________________________________ e. What type of lava would likely be present at point “x”? _______________________________ f. How many subduction zones are present in the image? _______________________________ g. Label a location that would be likely to have reverse(thrust) faults with the word “reverse”. 2. Japan is an island nation surrounded by subducting oceanic plates (see map). They also experience many large earthquakes and tsunamis, and have several active volcanoes. How many total tectonic plates are present on the map from point X to point Y? 3. What type of volcanoes are likely present in Japan? What type of lava are they most likely to have? 4. The image at right is of the Yellowstone supervolcano hotspot track, with the ages of each eruption labeled (in Millions of years). Which arrow shows the correct direction of plate movement? 5. What would be a global impact of a supervolcano eruption? 6. Which letter shows the southern hemisphere in spring? 7. Planetary Energy Balance. On the diagram below, draw and label: a) the flow(s) of energy that result from Earth’s “albedo”. (1) b) the flow(s) of energy to represent the greenhouse effect. (2) Tip - Make sure that you include the direction of travel and the correct type of radiation. 8. The map below shows sea level pressure in mbars over South America (southern hemisphere). a) Draw a star to mark the location on the map where there is the biggest pressure gradient and so the fastest winds. (1) b) Label X, Y, and Z as centers of high or low pressure: x = ________________________; y= _____________________, z= _______________________________ c) Draw arrows how winds would blow around location X (1) d) At which letter on the map would you likely experience clouds and rainfall? (1) ______________ Why? (1) _____________________________________________________________________________________________________ _____________________________________________________________________________________________________ e) What is the highest pressure reading on the map? (1) ______________________________________________ 9. The image at right shows magnetic reversals at a mid-ocean ridge, marked with a star. What is the age of rock M? 10. Which of the diagrams at right illustrates a star that is HOTTER than our sun, given the below emissions spectra? Our sun is labeled in the diagram. a. Star A b. Star B c. The sun is the hottest star in the diagram 11. In the image at right, zone X is ___________ and zone Y is _____________________: a. Unsaturated; Supersaturated b. Unsaturated; Unsaturated c. Supersaturated; Unsaturated d. Supersaturated; saturated 12. Where would evaporation occur at a rate that exceeds condensation? a. Zone X b. Zone Y 13. What is the Saturation Vapor Pressure of Parcel B? a. 10mb b. 30°C c. 40mb d. 10°C 14. Which parcel has greater actual vapor pressure? a. Parcel A b. Parcel B c. Both parcels have the same Actual Vapor Pressure 15. What is the dewpoint temperature of Parcel A? Parcel B?
