30. ■ Seafloor spread/mid-ocean ridges occur at divergent boundaries in the middle of the ocean. The two plates pull apart from each other, magma rises up from the mantle, and it cools and hardens into new rock. Geologic Activity - $400 Answer- $400 Answer Click to return to Jeopardy Board

31. Explain why earthquakes happen at transform boundaries. Geologic Activity - $500 Question- $500 Question Click to see answer

32. ■ When two plates rub together, it causes friction, and the pressure between the plates builds up. When the plates slip, it causes the earth to shake. Geologic Activity - $500 Answer- $500 Answer Click to return to Jeopardy Board

35. ■ Scientists have found fossils of the same animal species on multiple continents, but the animal could not swim, so how did the animal get to the different continents? Evidence - $200 Question - $200 Question Click to see answer

36. ■ If the animal wasn’t able to swim to the different continents, this suggests that the continents must have been connected. Evidence - $200 Answer - $200 Answer Click to return to Jeopardy Board

37. ■ Scientists know that plants and animals need a warmer climate to survive, yet we’ve found fossils in Antarctica – how’s that possible? Evidence - $300 Question - $300 Question Click to see answer

38. ■ This suggests that long ago Antarctica used to be located closer to the equator and had a warmer climate, and sometime in the past, it moved to its current location. Evidence - $300 Answer - $300 Answer Click to return to Jeopardy Board

39. ■ Summarize three pieces of evidence that led Alfred Wegener to his theory of “continental drift”. Evidence - $400 Question - $400 Question Click to see answer

40. ■ The shape of the continents appear to fit together, especially South America and Africa. ■ Fossils from the same dinosaur and plant species were found on multiple continents, suggesting the continents were once connected. ■ Fossils have been found on Antarctica which suggests that Antarctica used to be warmer and closer to the equator.

41. Explain what scientists predict will happen to our continents millions of years in the future. Evidence - $500 Question - $500 Question Click to see answer

42. Scientists believe that all of the continents used to be connected in a supercontinent called Pangaea and have moved apart throughout history. Thus, in the future, many believe that they will continue to move in the same direction and eventually meet on the other side of the planet.

62. –First, the rock would be “born” from magma, and it would cool and harden into a piece of igneous rock. –Over time, the igneous rock would be broken down into sediment/eroded by wind or water. –Then, the sediment would need to be deposited somewhere and compacted to turn it into a sedimentary rock. –That sedimentary rock would undergo years and years of heat and pressure inside of the Earth to become a metamorphic rock.
