| Term | Definition |
|---|---|
| Abyssal Plain: | An abyssal plain is a vast, flat, and relatively featureless area on the ocean floor that typically lies at great depths, usually between 3,000 and 6,000 meters (9,800 to 19,700 feet) below sea level. These plains are formed by the accumulation of fine |
| 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. It is usually covered by shallow seas and varies in width but can extend for hund |
| Continental Slope: | The continental slope is the steeply inclined transition zone between the continental shelf and the deep ocean floor. It marks the boundary where the continental crust gives way to the oceanic crust, and it often features submarine canyons and channels |
| Convergent Plate Boundary: | A convergent plate boundary is a tectonic boundary where two lithospheric plates are moving toward each other. When these plates collide, they can lead to various geological features such as mountain ranges, volcanic arcs, and ocean trenches. |
| Divergent Plate Boundary: | A divergent plate boundary is a tectonic boundary where two lithospheric plates are moving away from each other. At these boundaries, new oceanic crust is created as magma rises from the mantle and solidifies, forming mid-ocean ridges. |
| Mid-Ocean Ridge | A mid-ocean ridge is an underwater mountain range that runs through the center of many ocean basins. It is created by the divergence of tectonic plates, where new oceanic crust is formed as magma rises from the mantle and solidifies at the mid-ocean ri |
| Ocean Trench | An ocean trench is a long, narrow, and extremely deep depression on the ocean floor. Trenches are formed at convergent plate boundaries, where one tectonic plate is forced beneath another in a process called subduction. The Mariana Trench is the deepes |
| ROV (Remotely Operated Vehicle): | An ROV is a remotely operated underwater vehicle that is used for exploring and studying the ocean depths. ROVs are typically operated by remote control from the surface and are equipped with cameras, sensors, and robotic arms, allowing scientists and |
| Seamount: | A seamount is a submerged mountain rising from the ocean floor that does not reach the surface of the water. These underwater peaks can vary in size and shape and often host diverse marine ecosystems due to their upward protrusion into the open water. |
| Sonar (Sound Navigation and Ranging) | Sonar is a technology that uses sound waves to detect and locate objects underwater. It works by emitting sound waves and measuring the time it takes for those waves to bounce back after hitting an object. Sonar is widely used in navigation, mapping t |
| 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. Soundings help create nautical charts and maps of the ocean |
| Subduction: | Subduction is a geological process at convergent plate boundaries where one tectonic plate is forced beneath another into the Earth's mantle. This process often leads to the formation of deep ocean trenches, volcanic arcs, and seismic activity. |
