1. Earth Interdependence

2. What internal energy source is responsible for the convection currents in the earth’s asthenosphere?

3. What is responsible for the internal Energy source?  Radioactive Isotopes decay  Gravity  Left over from formation

4. What is the external energy source for the Earth?

5. Sun’s Nuclear Fusion  External Energy Source

6. What is the reason for the seasons on the earth?

7. Seasons We are closer to the Sun in the winter! Title on axis Sun’s path- time of direct sunlight

8. If the convection currents in the earth’s mantle were to stop, how would the number of earthquakes and volcanoes be affected?

9. There would be fewer (less #’s)

10. Why is the temperature on a cloudless winter night much colder than if there were cloud cover?

11. Clouds trap heat in! (like a blanket)

12. How do surface ocean currents affect climate?

13. Water has a high specific heat, so it stabilizes the climate. Hot chases cold, currents move heat from equator to poles.

14. As the wind flows down the leeward side of the mountain range, how would the air be different than the windward side?

15. Mountains cause a change in climate Windward wetLeeward dry and hotter

16. In which Earth layer are most convection currents that cause seafloor spreading thought to be located? Be specific!

17. Asthenosphere- upper mantle

18. How did scientist infer the outer core is liquid? Be specific!

19. Earthquake waves and the magnetic field it produces Geomagnetic probe. S-waves  Can’t travel through liquids, not enough energy. P-waves  Can travel through liquids slowly, and do travel through the Earth.

21. The Earth’s inner core is hotter than the liquid outer core, but it is still solid. Why?

22. Inner Core –Fe & Ni is Under Pressure!!

23. How can volcanic activity affect an areas temperature?

24. Spewing dust, ash and gases into the atmosphere.

25. Would Georgetown, KY need to worry about the effects of an Earthquake? Why?

26. YES! Limestone Bedrock is solid an the Madrid Fault runs through it.

27. A new island is forming slowly in the Hawaiian island chain. Explain why and which island is older.

28. Magma is rising to surface due to a HOT SPOT near the middle of a tectonic plate.

29. What forms when the sea floor spreads apart? Why?

30. Sea floor spreading= New land, trenches and volcanos

31. What is usually responsible for an earthquake?

32. Slippage along faults within the Earth’s crust Real?

33. What causes the magma inside a volcano to rise toward the surface? Think Pressure

34. High pressure due to rising temperature in a closed cavern; Show offs

35. How is the Earth’s surface changing over time?

36. Erosion and New formation

37. Mt Everest –Himalayas tallest

38. New mountains can be formed when land masses are being pushed together due to plate tectonics, and also from volcanic activity. Mount Everest and the rest of the Himalayas make up a relatively young Mt. Chain. What can you infer about Asia and India’s plates?

39. India moving to Asia
