Subduction is:

• process by which ocean crust is taken into the trenches and back to the mantle
• theory that new seafloor is formed when magma is forced upward toward the surface at a mid ocean ridge
• plates slide past each other in opposite directions
• a gradual movement of the continents across the Earth's surface over time
