| The faults appeared when Dr Oldenburg and Dr Brune tried to mimic sea-floor spreading by pulling the surface layer of their wax apart. In this section Sayonara, spaceflight? |
| During periods of accelerated sea-floor spreading and mid-ocean ridge activity, sea-levels rose so that parts of the continents were flooded and forests were destroyed. |
| Note the Moho near 1000 km in each frame, which was thinned by extension prior to the onset of sea-floor spreading. |
| Reversals of the Earth's magnetic field, allied to sea-floor spreading, have left their imprint in the form of a magnetic tape recorder on the sea-floor. |
| The main figure demonstrates how sea-floor anomalies, also known as magnetic stripes, develop during sea-floor spreading. |
| Create a poster that illustrates sea-floor spreading in the Atlantic ocean basin. |
