Seafloor Spreading- Oceanic plates spreading at a rate of 2.5 centimeters per year. Magnetic Field- an area around a magnet in which magnetism is felt. Plate Tectonics- the theory that lithospheric plates that move relative to one another collide in some places, pull apart in others and slide past one another in still others.
