Explain your answer. 38 4 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. 39 4 What is the order of the layers of the Earth from the surface to the center? ______________________ 40 5 What are Lithosphere, Asthenosphere, Mesosphere, Outer core, Inner core 41 5 Tectonic plates “float” on what ? ______________________ 42 1 What is Gondwana 43 1 The San Andreas Fault is an example of a ______________________ 44 2 What is a strike-slip fault. 45 2 Earth’s liquid layer ____________________. 46 3 What is outer core 47 3 Stress that stretches a rock layer____________________. 48 4 What is tension 49 4 Explain the process of subduction. 50 5 -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. 51 5
