During seafloor spreading, magma rises and hardens to form new crust, which becomes part of the ocean floor. Each cycle of spreading and intrusion results in the formation of another small section of ocean floor, which slowly moves away from the ridge. Section 17.2 Study Guide. Section 17.3 Main Ideas.
