23. When two plates run into each other and form MOUNTAINS!! Or one plate goes on top of the other plate and forms a subduction zone and volcanoes!

24. What is a divergent boundary???

25. A boundary in which tectonic plates pull away from each other and form land subsidence and mid ocean ridge

47. Ortelius

48. Which scientist came up with the Uniformitarian Principle and the Law of Superposition?

49. Hutton

50. What is the Law of Superposition??

51. Older rocks are deeper in the Earth than younger rocks.

52. What is the Uniformitarian Principle?

53. “The present is the key to the past..”

54. If you were studying the mid-ocean ridge, and you wanted to find the newest, “youngest” rocks, where would you look?

55. At the very center of the mountain

56. What is sea-floor spreading?

57. The process that continually adds new material to the ocean floor; the sea floor spreads as new crust is added
