Density of seawater is largely a function of two factors: depth, that is, the deeper water is more dense than water at shallower levels; and temperature - water at higher temperatures is less dense than cooler water. Salinity is also a factor, but that's a localized phenomena simply because all the worlds oceans are in fact one large ocean and maintains an average overall salinity.

What is a density independent factor of the benthic zone?
A density-independent factor of the benthic zone is an environmental factor that affects the populations of organisms regardless of their density, such as temperature fluctuations, physical disturbance, or changes in salinity. These factors can impact the benthic community by influencing reproduction, survival, and distribution of benthic organisms.
Was hurricane Andrew a density-dependent factor or a density-independent factor?
Hurricane Andrew would be considered a density-independent factor because its impact on a population does not change based on the population size or density. It affects all individuals in the same way regardless of the population's size.
What is the definition of a density independent limiting factor?
A density-independent limiting factor is a factor that affects a population regardless of its size or density. These factors include natural disasters like wildfires, hurricanes, and droughts, which can reduce population size even if the population is small.
What is one factor that decreases salinity in seawater?
Salinity in oceans decrease when near a river because the river adds fresh water, which lowers the percentage of salt in the water, causing the salinity to decrease.
Which is a density indepdent factor?
