australia is in the continent of australia it is both a continent and a country note contrary to erroneous opinion it is not in the continent of either aus tralasia or oceania neither of these is a geographical continent but rather they are both political regionst is sometimes referred to as an island continent because it is one of only two continents in the world completely surrounded by water australia is part of the geographic region of oceania which by definition is not actually a continent
So, the colder the water, the more dense it is. Increasing salinity also increases the density of sea water. Less dense water floats on top of more dense water. Given two layers of water with the same salinity, the warmer water will float on top of the colder water.
The density of seawater at the surface of the ocean varies from 1,020 to 1,029 kilograms per cubic meter. 1020â1029 kg/m3 The density of an object is the ratio of its mass to its volume. Density can also be expressed as specific gravity, which is the ratio of the density of a material to the density of water. Where the density of water in SI units is 1000 kilogram per cubic meter. The density of seawater varies with temperature and salinity of the water. As temperature increases, density decreases. As salinity of the water increasaes, density also increases. Although the density of seawater varies at different points in the ocean, a good estimate of its density at the ocean's surface is 1025 kilogram per cubic meter. Its specific gravity is therefore 1.025.
