neritic zone
sublittoral
The neritic zone is the part of the ocean that extends from the low-tide line to the edge of the continental shelf. It is characterized by warm, nutrient-rich waters and supports a wide variety of marine life, including fish, dolphins, and sea birds. The neritic zone is an important area for commercial fishing and provides a crucial habitat for many species.
Yes, the continental slope descends steeply from the continental shelf into the deep ocean floor. It marks the boundary between the continental crust and the oceanic crust.
The bottom of the ocean is part of a tectonic plate or continental shelf, or can be on the breach line between two shelves.
The continental shelf begins at the shoreline and extends underwater to a depth of about 200 meters, where it gradually slopes down to the continental slope. This region is characterized by relatively shallow waters and is rich in marine life, making it a vital area for fishing and resource extraction. The shelf plays a crucial role in supporting ecosystems and provides important habitat for various species. Beyond the shelf lies the deeper ocean floor, which is part of the continental rise and abyssal plain.
Continental Line was created in 1898.
a grounding line is a line at the edge of the ice shelf
If an ocean trench is located west of volcanic islands, you can assume that there is a continental shelf nearby. You can also assume that the trench is at least 7000Êm deep.
The continental slope is the steep transition between the continental shelf and the deep ocean floor, marking a distinct boundary in underwater topography. This area typically descends at an angle of 2 to 5 degrees, leading to the abyssal plain. It serves as a critical ecological zone where nutrients from the shelf can flow into deeper waters, supporting diverse marine life. Additionally, the slope is important for geological studies and resource exploration, including oil and gas deposits.
According to the British Antarctic Survey:"The Ross Ice Shelf is the largest ice shelf of Antarctica (an area of roughly 487,000 square kilometres ((188,000 sq mi)) and about 800 kilometres (500 mi) across: about the size of France)."
