Why does only 10 percent of the iceberg float on top of water?
Yes. The rule of thumb is 20 percent is visible above the water. Yes, they do float, however i believe that it's 10% that is visible due to the density of ice (0.9 g/cm) and the density of water (1g/cm). So .1 or 1 tenth of the iceberg is above the surface. (10%)
Will seawater expands when frozen into iceberg?
Yes, seawater expands when frozen into an iceberg because the density of ice is lower than that of liquid water. As the water freezes and forms into ice, it occupies more space, causing it to expand. This expansion is what causes icebergs to float with a portion visible above the water's surface.
How much can an iceberg be seen above the water?
Typically, only about 10% of an iceberg is visible above the water's surface, with the remaining 90% submerged. This is due to the density of ice being lower than that of seawater. The visible portion can vary greatly in size and shape, depending on the iceberg's overall dimensions and the conditions of the surrounding water.
How are density and salinity related?
Density and salinity are directly related in seawater - as salinity increases, the density of seawater also increases. This is because dissolved salts and other substances in seawater add mass without significantly changing the volume, thereby increasing the overall density. Conversely, a decrease in salinity will lead to a decrease in density.
What percentage of an iceberg is below water and why?
Well, honey, about 90% of an iceberg is below the water because that's just how physics works. The density of ice is lower than that of water, so the iceberg floats with a whole lot hidden beneath the surface. Just like an iceberg, there's always more to a situation than meets the eye.

The relative density of seawater is 1.03 and of ice is 0.92. What fraction of an iceberg is above the surface of the water?
79% of an iceberg is underwater, so 21% or about one fifth is above it. However given the shape and size of an iceberg, as little as 10% can be above water at times, so it can be between one tenth and one ninth above water.
Will seawater expands when frozen into iceberg?
Yes, seawater expands when frozen into an iceberg because the density of ice is lower than that of liquid water. As the water freezes and forms into ice, it occupies more space, causing it to expand. This expansion is what causes icebergs to float with a portion visible above the water's surface.
What is the most important factor affecting seawater density?
The most important factor affecting seawater density is its temperature. As temperature increases, seawater density decreases, causing it to expand and rise. Conversely, as temperature decreases, seawater density increases, causing it to contract and sink.
How density current forms?
Density currents - more dense seawater sinking beneath less dense seawater.
What are 2 main factors that influence density if seawater?
Temperature and salinity are the two main factors that influence the density of seawater. Colder seawater is denser than warmer seawater, while seawater with higher salinity is denser than seawater with lower salinity.
What is the mass of the iceberg (relative density of sea water 1.02 and relative density of ice 0.9)An iceberg floating in sea water just sinks when a mass of 360 kg is placed on it .?
The buoyant force on the iceberg when the 360 kg mass is placed on it is equal to the weight of the added mass. We can use the concept of relative density (or specific gravity) to find the mass of the iceberg, knowing that it displaces its own weight in water. By applying the principle of buoyancy, we can calculate the iceberg's mass to be around 400 kg.
Does ice go below freezing temp?
The average density of pure ice is about 920 kg/m³. The average density of seawater is about 1025 kg/m³. By Archimedes's principle, the mass of the seawater displaced (i.e. the amount of the iceberg underwater) should equal the mass of the iceberg. Using that principle, for each 1 m³ of seawater displaced it takes 1025 kg of ice - which will have a volume of 1025 kg x 1 m³/920 kg = 1.114 m³. In other words, 1m³ of the iceberg is submerged for every 1.114 m³ of iceberg. 1/1.114 = 0.89756 So, on average about 90% of the iceberg is submerged. If the seawater is a little less salty, more of the iceberg is submerged. If the iceberg is "dirty" - with stuff in it that is more dense than ice, more of the iceberg is submerged. If the iceberg has voids (air pockets) it will be less dense and less of the iceberg is submerged.
Does salt content of water affect the density of seawater?
the salt makes seawater denser than freshwater. more salt increases the density
What causes the density current in the mediterranean?
the answer to this question is a density current forms when more dense seawater sinks beneath less dense seawater
What causes the density in the mediterranean sea?
the answer to this question is a density current forms when more dense seawater sinks beneath less dense seawater
What fraction of iceberge is below the water line?
Approximately 9/10 of an iceberg is below the water. The figure is approximate because the density of the berg depends on how must the ice is compacted and how much air it contains. It also depends on the density of the seawater which, in turn, depends on its salinity and temperature.
