  2. Geology Part 1

  3. What is Wegener’s hypothesis of continental drift… • The continents were once joined together in a single landmass.

  4. Where are mid-ocean ridges located? • In all of Earth’s oceans

  5. What did scientists in a submersible see when they observed the mid-ocean ridge? • Rocks formed by the rapid hardening of molten material

  6. What is Pangaea? • The name of the supercontinent that existed millions of years ago

  7. What type of boundary forms when two plates come together? • Convergent boundary

  8. What type of boundary is formed by two plates slipping past each other, moving in opposite directions? • Transform boundary

  9. A rift valley is formed at which type of boundary? • Divergent boundary

  10. What technology did scientists use in the mid-1900’s to map the mid-ocean ridge? • sonar

  11. What is shearing? • Stress that pushes a mass of rock in two opposite directions

  12. What is a fold in rock that bends upward into an arch called? • anticline

  13. What can cause damage days or months after a large earthquake? • aftershock

  14. What is a large area of flat land elevated high above sea level called? • plateau

  15. What is a force that acts on rock to change its shape or volume called? • stress

  16. What is the point beneath Earth’s surface where rock breaks under stress and triggers an earthquake called? • focus

  17. Which scale would most likely be used to tell how much earthquake damage was done to homes and other buildings? • Mercalli scale

  18. What is the rating system that estimates the total energy released by an earthquake called? • moment magnitude scale

  21. Water and Atmosphere Part 2

  22. On average, a snowfall of 20 centimeters would equal a rainfall of how many centimeters? • 2 centimeters

  23. Isobars are lines on a map joining places that have the same what? • air pressure

  24. What are high feathery clouds called? • cirrus clouds

  25. What kind of weather would a continental tropical air mass that formed over northern Mexico bring to the southwestern United States? • hot and dry

  26. The collecting of weather data in the last 40 years has improved mostly by what? • balloons and satellites

  28. The Human Body Part 3

  29. This heart structure prevents blood from flowing backward. • valve

  30. This causes blood pressure. • The force with which the ventricles contract

  31. Condition in which artery walls thicken as the result of a buildup of fatty materials. • atherosclerosis

  32. This system carries messages back and forth between the brain and other parts of the body. • nervous system

  35. These three things work together to make your body move. • muscles • bones • nerves

  36. This is a structure composed of different kinds of tissue, such as the brain. • organ

  37. This system breaks down food so the body can use it. • digestive system

  38. This structure directs the activities of a cell. • nucleus

  39. This type of body tissue can contract, or shorten. • muscle tissue

  40. This disrupts homeostasis. • long-term stress

  41. Chemicals produced by the endocrine system that control both daily activities and long-term changes. • hormones

  42. Body part where two bones come together. • joint

  43. These activities can help prevent getting a cold. • socializing • exercising • getting sleep

  44. This is the process of nutrients moving into the bloodstream from the digestive system. • absorption

  45. Transporting oxygen is a function of this system. • circulatory system

  46. This is the process by which an organism’s internal environment is kept stable in spite of changes in the external environment. • homeostasis

  48. Substance that you get from food and that your body needs to carry out processes. • nutrient

  49. These organs release chemical signals directly into the bloodstream. • glands

  50. This is what happens to the muscle when bending a joint. • contracts
