Do Now: Copy the following statements and state whether the following statements are true or false in your Science Notebook Seafloor spreading takes place along a mid-ocean ridge. True Oceanic crust is older when it is closer to a mid-ocean ridge than it is when it is farther from the ridge. False, it is younger when it is closer to a mid-ocean ridge. The high thermal-energy flow at a mid-ocean ridge comes from seawater. False, the thermal energy comes from magma.
