The sea floor spreading apart whgule magma rises and hardens to make a new ocean floor. age of ocean crust and where volcanoes and earthquakes are is the evidence
11) describe the age of the seafloor in comparison to the mid ocean ridge
the age of the sea floor gets older as you move away from the mid ocean ridge
