What defines the pelagic zone of the ocean?

The pelagic zone of the ocean is characterized as the expansive area of open water that exists beyond the continental shelf. This zone is distinguished by its depth and the fact that it comprises deeper waters, providing a unique ecosystem that is different from coastal and shallow areas.

In the pelagic zone, organisms are generally free-swimming or drifting in the ocean's depths, as it includes both the water column and the deeper parts of the ocean. The conditions in this zone can vary widely, with factors such as temperature, light penetration, and pressure differing significantly as one moves deeper into the ocean.

Understanding the pelagic zone is crucial for recognizing the biodiversity and the ecological dynamics at play in these offshore areas, as well as their role in global ocean currents and climate patterns.
