This activity/lab takes between 2-3 class periods and includes all student material, answer keys, and diagrams. It is a great way to review or reinforce that the Earth’s plates are in motion as we speak. This activity/lab will let students collect actual data using measurements from the Mid-Atlantic Ridge to determine the rate at which the plates are moving (sea floor spreading). This is all driven by convection currents within the Earth’s mantle.
