pages and answer the questions below IN COMPLETE SENTENCES Complete the activities on the next three pages and answer the questions below IN COMPL Data and Maps obtained from: http:/lvortex.plymouth edu/sfowx.tu.html faceTemperaturevs. Humidity Maps l. Draw temperature contour lines every i0 (eg, 30°F, 40°F, 50°F) 2. What is the general relationship between temperature and latitude? These data are from midnight on April I. What is generally warmer, the air above the ocean or the land? 3 3. Why is that? 4. Focusing on the central US, what is the general relationship between temperature and relative humidity (e g. compare Texas with Nebraska). 5. Compare the circle areas in the US Southwest versus Southeast. These areas are similar in temperature- what accounts for the difference in relative humidity? 6. Notice the circled area in California and the dramatically lower humidity values. What can account for this? 7. What accounts for the relatively higher humidity values in and around Michigan? 8. At what two locations is it definitely raining? Atmospheric Pressure vs. Wind Direction and Strength Maps 9. Draw pressure contour lines every 5 mbars (c.g. 995 mb, 1000 mb, 1005 mb) 10. Draw a large L representing the low pressure center on the pressure and surface wind maps. How would you describe the wind pattern around this low pressure center (strong/weak, circular/straight, clockwise/counterclockwise)? 11. Draw a large H representing the highest pressure areas on both maps. How would you describe the wind patterns around the high pressure center (strong/weak, circular/straight, clockwise/counterclockwise)? 12. What major weather-producing phenomenon is shown in the interesting pattern of winds around WI, MN, IL and IA? 13. Shade in the areas where you think there is precipitation. Surface Cloud Cover vs. Frontal Systems Maps 14. What is the relationship between frontal systems and cloud cover? 15. Draw the following air masses on the frontal systems map (cP, mT, mP, cT). 16. Draw the generally expected wind direction between the high and low pressure centers. 17. Draw the symbols on the lines for the warm, cold, and occluded fronts on the frontal systems map. 18. What weather would you expect the next day for Virginia? Why? 19. What weather would you expect for central Tennessee? Why? 20. How about for Michigan?Explanation / Answer
A continental hot spot develops above the mantle. Here the magma rises through the rigid plates of the lithosphere and produce active volcanoes at Earth surface.
Divergent plate boundaries are locations where plates are moving away from one another. This occurs above rising convection currents. The rising current pushes up on the bottom of the lithosphere, lifting it and flowing laterally beneath it. This lateral flow causes the plate material above to be dragged along in the direction of flow. At the crest of the uplift, the overlying plate is stretched thin, breaks and pulls apart. This result in Mid Oceanic Ridges.
A tectonic setting where volcanism occurs is called intraplate- or hot-spot-volcanism, which describes volcanic activity that occurs within tectonic plates .
Most volcanic activity occurs at plate boundaries, but there are also a large number of volcanoes located with a plate, some of which are exceptionally active. These areas of so-called intraplate volcanism are called hot spots.
A subduction zone is a boundary where two tectonic plates collide and, because of differences in density, one dives beneath the other. This occurs frequently where an oceanic plate meets a continental plate. The denser and thicker oceanic plate is shoved underneath the less dense continental plate
