| Subduction zone | | Continental crust consists mostly of this mineral |
| Tidal range | | Salinity is expressed using these conductivity measurements |
| Sediment | | Continuous submarine range of volcanic mountains that run throughout the ocean basins |
| Hot spot | | Process by which the sea floor moves away from the mid-ocean ridges to create new sea floor |
| Seamounts | | Oceanic crust consists mostly of this mineral |
| Granite | | Deep-sea hot springs laden with dissolved minerals/nutrients from the earth's mantle |
| Crest | | Deflection of large scale motions such as winds or currents |
| Sea-floor spreading | | Difference in water level between successive high and low tides |
| Hydrothermal Vents | | Loose material like mud and sand that settles on the ocean floor |
| Continental slope | | Away from the wind, waves settle into these |
| Hydrogen bonds | | Begins at shelf break and descends to deep-sea floor |
| Asthenosphere | | Boundaries between continental crust and oceanic crust |
| Mid-ocean ridges | | Biogenous sediment is often referred to as this because it consists of the preserved remains of dead organisms (mostly tiny ones) |
| Coriolis Effect | | Multiple deep-sea fans that have merged together will form this |
| Density | | Plastic layer of upper mantle |
| Continental margins | | Uppermost part of the mantle |
| Practical Salinity Units | | Mass per unit of volume |
| Lithosphere | | Downward movement of a plate into the mantle |
| Continental shelf | | Submarine volcanoes |
| Basalt | | Volcanic island chain associated with trenches (in general, 2 words, 1 space) |
| Swells | | Highest part of a wave |
| Weathering | | Extension of a continent underwater, has a gentle slope, and varies in width |
| Microfossils | | The chemical or physical breakdown of rocks |
| Continental rise | | Attractions between liquid water molecules that affects the freezing and thawing of water |
| Island arc | | Caused by the gravitational pull of the moon and sun and by the rotation of the earth, moon, and sun |
| Pangaea | | Name of the "supercontinent" originally proposed by Wegener |
| Tides | | Area of consentrated volcanic activity |
