Oceans

Oceans are large bodies of salt water covering approximately 71% of Earth’s surface and forming the main component of the hydrosphere. They regulate climate and weather by storing heat and circulating water, carbon, and nutrients, and support most marine life, including plants, animals, and microscopic organisms. Oceans are divided into horizontal zones, such as continental shelves and open ocean, and vertical zones, including the photic, mesopelagic, and aphotic layers. Ocean currents transport water, heat, gases, and nutrients globally, while human activities along coasts and in open waters impact ecosystems and contribute to pollution, overfishing, and climate change effects such as warming, acidification, and sea level rise.
