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.
What factor affects the density of seawater in addition to salinity?
Temperature is another significant factor that affects the density of seawater. As temperature decreases, seawater becomes denser and sinks, while warmer seawater is less dense and rises. The interactions between salinity and temperature play a crucial role in driving ocean currents and circulation patterns.
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 causes seawater to become more dense?
Seawater becomes more dense when the temperature decreases or when salinity increases. Cold water is denser than warm water, and water with higher salt content is denser than water with lower salt content.
What is the average salinity in the oceans?
The average salinity of seawater is 35 parts per thousand (or ppt).
Which is not a process the decreases the salinity of seawater?
Evaporation is a process that increases the salinity of seawater, not decreases it. Other processes that decrease the salinity of seawater include precipitation, melting of icebergs, and the input of freshwater from rivers.
Is not a process that decrease the salinity of seawater?
evaporation
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.
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.
What factor affects the density of seawater in addition to salinity?
Temperature is another significant factor that affects the density of seawater. As temperature decreases, seawater becomes denser and sinks, while warmer seawater is less dense and rises. The interactions between salinity and temperature play a crucial role in driving ocean currents and circulation patterns.
How does the salinity of sea ice compare to the salinity of normal seawater?
Ice has zero salinity. When it is frozen, the salt is pushed out. Therefore, since the salinity of normal seawater is about 35 ppt, it has 35 ppt more salinity than 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 average salinity of seawater by weight?
The average salinity of seawater is about 35 grams of dissolved salts per kilogram of seawater, or 3.5% by weight.
Amount of gas that seawater can hold in solution will be greater when?
The amount of gas that seawater can hold in solution will be greater when the water temperature is lower, the salinity is higher, and the pressure is higher. These factors can influence the solubility of gases like oxygen and carbon dioxide in seawater.
Which process does not add salts to seawater?
Storms at sea. The evaporated water falls back into the ocean with no net effect on salinity.
Is the following sentence true or false the average salinity of seawater is 35 percent?
False. The average salinity of seawater is actually around 3.5%, not 35%.
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.
