Describe the relationship between temperature, density, salinity and depth.
Temperature increases with depth, and salinity decreases with depth due to processes like evaporation and freezing. Therefore the density also increases.
Temperature increases with depth, and salinity increases with depth due to processes like evaporation and freezing. Therefore the density also decreases.
Temperature decreases with depth, and salinity increases with depth due to processes like evaporation and freezing. Therefore the density also increases.
