AP BIOLOGY

Detailed explanation-1: -But as in weather, where there are areas of high and low pressure, there are areas of high and low salinity. Of the five ocean basins, the Atlantic Ocean is the saltiest .

Detailed explanation-2: -The aquatic biome is divided into freshwater and marine regions. Freshwater regions, such as lakes and rivers, have a low salt concentration. Marine regions, such as estuaries and the ocean, have higher salt concentrations.

Detailed explanation-3: -Marine biomes have more salt and are characteristic of the oceans, coral reefs, and estuaries. Most aquatic organisms do not have to deal with extremes of temperature or moisture.

Detailed explanation-4: -The Average is 35 ppt. Salinity varies geographically according to precipitation, discharge from rivers, and evaporation (a function of temperature).

Detailed explanation-5: -The marine biome is the aquatic biome characterized by high salinity in the water. The salinity is high enough for this water to be classified as saltwater.
