What else can I help you with?
Coral reefs form in which portion of the Continental margin?
continental shelf
What is the name of the oceanic zone?
The oceanic zone is the name of the open ocean region beyond the continental shelf, characterized by deep waters with low nutrient levels and high pressure.
What kind of animals live in the continental shelf?
The continental shelf is home to a variety of benthic animals that live buried at the bottom of the ocean. Examples of some are, common whelk, blue mussel, Neptune whelk. periwinkle, Yoldia hyperborea, sand gaper, limpet, scallop, chiton, common starfish, green sea urchin, brittlestar, ragworm, pectinaria worm, scaleworm, skeleton shrimp, isopod, barnacle, benthic amphipod
How does the amount of nutrients in the water decreases as the distance from the continental shelf increases effect the open ocean food chains?
A decrease in nutrients as distance from the continental shelf increases can lead to reduced primary productivity in the open ocean. This in turn affects the entire food chain, as fewer nutrients means fewer phytoplankton, which are the base of the marine food web. This can result in less food available for higher trophic levels, impacting the overall biodiversity and ecosystem dynamics in the open ocean.
What is the shelf life of beeswax?
The shelf life of unopened petroleum jelly is around 3 years.
Why do commercial fisherman do not fish beyond the continental shelf?
Commercial fishermen typically do not fish beyond the continental shelf due to several factors, including the increased costs and logistical challenges associated with deep-sea fishing. The waters beyond the shelf are often deeper, making it more difficult and expensive to access, and the fish species available may not be as abundant or commercially viable. Additionally, regulatory restrictions and environmental concerns can limit fishing activities in these areas. Finally, many commercial fisheries are focused on species that are more readily available in shallower waters.
A sharp drop-off beyond the continental shelf is called what?
A sharp drop-off beyond the continental shelf is called a continental slope. The continental slope marks the transition between the continental shelf and the deep ocean floor.
In which zone do commercial fisherman seek large catches?
Commercial fishermen typically seek large catches in the continental shelf zone, which extends from the shoreline to the edge of the continental plate. This area is rich in nutrients and supports diverse marine life, making it ideal for fishing. Additionally, fishermen often target specific regions within this zone, such as fishing banks and upwelling areas, where fish populations are particularly abundant.
Why do fisherman not fish beyond the continental shelf?
Because for the most part, the continental shelves are where the fish are.
List three differences between the continental shelf and the abyssal plain?
The continental shelf is an extension of the cotton, only beneath water. The continental slope begins beyond the shelf and slopes downward.
What is the shallow extension of the continent that extends beyond the shoreline called?
The shallow extension of the continent that extends beyond the shoreline is called a continental shelf. It is the submerged part of a continent that extends from the shoreline to a drop-off point called the shelf break.
Which ocean environment extends seaward beyond the continental shelf?
Deep ocean basin
What is the oceanic zone?
The deepest, darkest area of the ocean that is beyond the edge of the continental shelf.
The portion of land that extends into the ocean is called the continental?
shelf
What is the difference between the continental slope and the continental rise?
The continental shelf starts from the shore to a few miles out with less gradient of slope. The continental slope starts after shelf-break with a higher slope gradient, then follows the continental rise and abyssal-plain.
What zone is not included in the continental margin?
The abyssal zone is not included in the continental margin. It is the deep ocean floor beyond the continental shelf, slope, and rise.
What lies under the ocean at the edge of a continent?
At the edge of a continent under the ocean lies the continental shelf, a gently sloping extension of the continent covered by shallow seas. Beyond the continental shelf, there is a steeper drop-off known as the continental slope, leading to the deep ocean floor of the abyssal plain.
