Abyssal Plain | An abyssal plain that is a vast, flat, and relatively featureless area on the ocean floor. |
Continental Shelf | The continental shelf is the gently sloping, submerged portion of a continent that extends from the shoreline to a marked increase in slope called the continental slope. |
Continental Slope | The continental slope is the steeply inclined transition zone between the continental shelf and the deep ocean floor. |
Convergent Plate Boundary | A convergent plate boundary is a tectonic boundary where two lithosphere plates are moving toward each other |
Divergent Plate Boundary | A divergent plate boundary is a tectonic boundary where two lithosphere plates are moving away from each other. |
Mid-Ocean Ridge | A mid-ocean ridge is an underwater mountain range that runs through the center of many ocean basins. |
Ocean Trench | An ocean trench is a long, narrow, and extremely deep depression on the ocean floor. |
Seamount | A seamount is a submerged mountain rising from the ocean floor that does not reach the surface of the water. |
Sonar (Sound Navigation and Ranging) | Sonar is a technology that uses sound waves to detect and locate objects underwater. |
Sounding | Sounding refers to the measurement of the depth of a body of water, typically the ocean, using various methods such as sonar, echo sounding, or physical measurement with a lead-weighted line. |
Subduction | Subduction is a geological process at convergent plate boundaries where one tectonic plate is forced beneath another into the Earth's mantle. |
ROV (Remotely Operated Vehicle) | An ROV is a remotely operated underwater vehicle that is used for exploring and studying the ocean depths. |
