Describe the oceans and explain how the water cycle affects the salinity of the ocean?
Oceans are big water bodies. Salinity is due to the presence of minerals in water.
How do oceanographers measure the salinity of ocean water?
Oceanographers measure the salinity of the ocean by hand held refractometer, hydrometer, and conductivity meter.
What is the salinity in the oceans?
The amount of salt in the water. Near the surface of the open oceans salinity is in general between 3.3% and 3.7%
How do temperature and salinity relate to deep-current movement?
The density of the water increases with the salinity, so saline water is denser and sinks to the bottom. Temperature is also a factor, however. Cold, saline water is the densest
How do you find the chemical analysis of water in the Jordan River Dead Sea Mediterranean Sea or the Sea of Galilee?
Partial answer: The salinity of the dead sea is ~31.5% by weight while the salinity of the Mediterranean is ~3.5%
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.
In general the density of sea water increases as?
salinity increases and temperature decreases....
The density of sea water increases as?
the density of sea water increases as salinity increases and temperature decreases
What is effect salinity and temperature have on water density?
Salinity and temperature both affect water density. As salinity increases, water density also increases because salt water is denser than freshwater. Similarly, as temperature decreases, water density increases due to the water molecules becoming more tightly packed together.
How does evaporation affects salinity?
Evaporation leaves salt behind. So as ocean water decreases, the percentage of salt increases, increasing salinity. As evaporation increases, rainfall also increases, thus it decreasing the salinity of ocean water.
What is the relationship between evaporation and precipitation rates and salinity?
Evaporation increases salinity in bodies of water by leaving behind dissolved salts, while precipitation decreases salinity by diluting the water. Higher evaporation rates in a body of water can lead to increased salinity over time, while frequent precipitation events can help maintain or lower the salinity levels.
What two factors can affect salinity?
Ocean currents,The sun,and human activities
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 the relationship between salinity and evaporation Proportional or inversely proportional?
The relationship between salinity and evaporation is inversely proportional. As salinity increases, the rate of evaporation decreases because higher salinity makes it harder for water molecules to escape into the atmosphere. Conversely, lower salinity allows for faster evaporation rates.
Describe the salinity of the ocean in terms of the concentration of salts?
It is estimated that every 1000g of water contains 35g of dissolved salts.Thus,the average salinity is 35 per thousand.In general,salinity decreases towards the equator due to heavy rainfall.
What is a measure of how salty water is?
Salinity is a measure of the saltiness of water.
What best describes the change in salinity in an estuary at low tide (as water leaves the area)?
At low tide, as water leaves the estuary, salinity typically increases. This occurs because the volume of freshwater from rivers decreases, reducing the dilution effect of freshwater on the seawater. Consequently, the concentration of salt in the remaining water becomes higher, leading to elevated salinity levels. Additionally, evaporation may also contribute to this increase in salinity.
