Question

Describe salinity with its depth

Answer 1

Salinity refers to the saltiness or mineral content of water. In the ocean, salinity typically increases with depth. This is because when water evaporates at the surface, salt is left behind, causing the water to become more saline. Additionally, deep ocean currents may bring saltier water from other regions to deeper depths. The average salinity of the ocean is around 35 parts per thousand, but this can vary depending on location and depth. The salinity gradient in the ocean is an important factor in determining ocean circulation patterns and the distribution of marine life.
