the density of sea increases with depth
depth and salinity increases density of sea water increases
A rapid change in density with depth in the ocean is called a thermocline.
the density of sea increases with depth
Pressure increases the density of sea water because it compresses the water molecules closer together, reducing the volume occupied by the same amount of water. As pressure increases with depth in the ocean, the density of sea water also increases. This effect is known as compressibility.
Since liquid pressure is function of density,acceleration due to gravity and depth of liquid level so here density of sea water is greater than that of river water ,so liquid pressure in sea must be more.
A rapid change in ocean density with depth is called a thermocline. This thermocline is caused by variations in temperature and can impact ocean circulation and marine life distribution.

The density of the Philippine Sea, like other oceanic waters, varies with depth, temperature, and salinity. Generally, seawater has an average density of about 1.025 grams per cubic centimeter (g/cm³) in this region. However, this value can change due to local environmental factors, including ocean currents and temperature gradients.
A rapid change in temperature with depth in the ocean is called thermocline. A rapid change in density with depth in the ocean is called the pynocline.Thermocline
Otters can change their density to either float on the surface of the water, or sink. Therefore, their density can vary.
the density does not change, only the pressure
The density of seawater increases with depth due to the increased pressure at greater depths compressing the water molecules closer together. This increased density can also be influenced by temperature and salinity variations within different layers of the ocean.
