Ques: Answer the following question given this paragraph: Convection within the Earth's mantle causes the plates to move. Mantle material is heated above the core. The hot mantle rises up towards the surface ( Figure below ). As the mantle rises it cools. At the surface the material moves horizontally away from a mid-ocean ridge crest. The material continues to cool. It sinks back down into the mantle at a deep sea trench. The material sinks back down to the core. It moves horizontally again, completing a convection cell. Q: What does convection within the earth's mantel cause? Choices: - volcanos - hurricanes - microorganisms to move - plates to move A:
Ans: plates to move
