38. 38 What is the major evidence that sea- floor spreading creates new lithosphere? Explain your answer. 4

39. 39 What is -Molten rock at mid-ocean ridges has magnetized minerals that align with Earth’s magnetic field -When the Earth’s magnetic field reverses, the magnetized minerals align in the opposite direction -The record of magnetic reversals is carried away from each side of the spreading center of a mid-ocean ridge, showing that the molten rock is creating new lithosphere. 4

50. 50 Explain the process of subduction. 5

51. 51 -oceanic plate is forced beneath a less dense oceanic or continental plate at a convergent boundary -Gravity pulls the oceanic plate into the hot asthenosphere, which causes melting. 5
