Seawater, or sea water, is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of about 3.5% (35 g/L, 35 ppt, 600 mM). This means that every kilogram (roughly one liter by volume) of seawater has approximately 35 grams (1.2 oz) of dissolved salts (predominantly sodium ( Na +
The World Ocean. For example, the Law of the Sea states that all of the World Ocean is "sea", [8] [9] [10] [b] and this is also common usage for "the sea". Any large body of water with "Sea" in the name, including lakes. River – a narrow strip of water that flows over land from a higher elevation to a lower one; Tributary – a small river ...
The terms "the ocean" or "the sea" used without specification refer to the interconnected body of salt water covering the majority of Earth's surface. [10] [11] It includes the Pacific, Atlantic, Indian, Southern/Antarctic, and Arctic oceans. [19] As a general term, "the ocean" and "the sea" are often interchangeable. [20]
This is a list of bodies of water by salinity that is limited to natural bodies of water that have a stable salinity above 0.05%, at or below which water is considered fresh. Water salinity often varies by location and season, particularly with hypersaline lakes in arid areas, so the salinity figures in the table below should be interpreted as ...
A sea is a large body of salt water. There are particular seas and the sea. The sea commonly refers to the Ocean, the interconnected body of seawaters that spans most of Earth. Particular seas are either marginal seas, second-order sections of the oceanic sea (e.g. the Mediterranean Sea), or certain large
Though generally described as several separate oceans, the world's oceanic waters constitute one global, interconnected body of salt water sometimes referred to as the World Ocean or Global Ocean. [1] [2] This concept of a continuous body of water with relatively free interchange among its parts is of fundamental importance to oceanography. [3]
Sea salt is made by evaporating ocean water or water from saltwater lakes. Unrefined sea salt is minimally processed, retaining trace minerals that might lend color or flavor to the salt. (Refined ...
Salt marshes can be generally divided into the high marsh, low marsh, and the upland border. The low marsh is closer to the ocean, with it being flooded at nearly every tide except low tide. [25] The high marsh is located between the low marsh and the upland border and it usually only flooded when higher than usual tides are present. [25]
