Oceanic zones are distinct regions of the ocean, each characterized by different environmental conditions and life forms. The main zones include the intertidal zone, where the ocean meets the land, the neritic zone, which extends from the shore to the continental shelf, and the oceanic zone, which covers the open ocean. These zones vary in depth, light availability, and temperature, influencing the types of organisms that can thrive in each area. The ocean is further divided into vertical zones based on depth, such as the photic zone, where sunlight penetrates, allowing photosynthesis, and the aphotic zone, where light does not reach. Below these, the benthic zone refers to the ocean floor, while the abyssal zone is the deep-sea area, characterized by extreme pressure and cold temperatures. Each zone supports unique ecosystems and biodiversity.
