The deeper the water gets the more water there is. Think of it like bricks, the more you put on the pile, the heavier it gets because there is more weight on the bottom bricks.
the dead sea
usaully 1.93% but this varies wit depth and location
the sea water contains more salt. the pure water do not contain salt. the density of sea water is more than density of pure water. as there is more salt in sea water it is corrosive against the metals like aluminium. the pure water is not corrosive in nature. sea water is harmful for drinking. pure water is good for drinking.
There are many factors which determines the color of the sea/ocean, The reflectivity of the water has an important role in the color of ocean.The color of ocean is generaly blue because the water reflects the image of the sky which is in blue color. But there are other factors also there which determine ocean color,The depth of the ocean,presence of colored algae and fine suspende solid particles. Near to the shore the nutrient suply from the land will be high and because of that the density of algaes and phytoplankton will be more which gives a different color to the water near to the sea shore.
Density always increases as altitude decreases. So the air density below sea level will be greater than the air density at sea level.
the density of sea increases with depth
the density of sea increases with depth
depth and salinity increases density of sea water increases
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.
Otters can change their density to either float on the surface of the water, or sink. Therefore, their density can vary.
The "weight" of the water is an ambiguous term that could be referring either to the water pressure or the density. Even though the water pressure increases with depth, the density of the water doesn't change much. So anything that sinks on the surface will generally go to the bottom regardless of depth. There are some layered variations in salinity that can cause some density variations, and there might be a few materials whose density is very close to sea water that could reach a region in which they would be suspended.
the density does not change, only the pressure
Salt water is more dense than fresh water. The added density adds pressure, so the pressure will be greater at the same depth in salt water. This is also the cause of the increase of buoyancy in saltwater.
the density of sea water increases as salinity increases and temperature decreases
Sea water and fresh water does not have the same density because sea water has salt, which makes it more dense than fresh water Sea water and fresh water does not have the same density because sea water has salt, which makes it more dense than fresh water
Sea water has salt, and therefore a higher density.
sea water has a higher density
