Does heavy rainfall make ocean water more or less dense?
Heavy rainfall makes water less dense because an increase in salinity leads to an increase in density. Rain does not contain any salt. Therefore heavy rainfall makes ocean water less dense. =)
What is the average density of seawater?
The density of surface seawater ranges from about 1.020 to 1.029 g·cm-3, depending on the temperature and salinityThe average density of seawater at the surface of the ocean is 1.025 g/ml; seawater is denser than freshwater (which reaches a maximum density of 1.000 g/ml at a temperature of 4°C) because of the added mass of the salts.
What water temperature increases density of ocean water?
When the ocean water freezes, it increases the salinity. When the ocean water freezes at the surface, ice will float on top of water because ice is less dense than liquid water. The dissolved solids are squeezed out of the ice and enter the liquid water below the ice. This increases the salinity of the water. The density of the water also increases.
Why is surface salinity of an ocean higher in the subtropics than in the equatorial regions?
Evaporation is more. Rainfall is less in comparison of equatorial region. In equatorial region, insulation is not much because of clouds.
What ocean has the most salt in it?
The saltiest part of the sea can be found in Sargasso Sea which is located within the North Atlantic Ocean. The saltiness of the sea is due to the high water temperature which is up to 83º F.
The average ocean salinity is less than 4.?
True
What are three areas in the ocean where salinity may be less than average?
Where a major river enters. Where a large glacier enters. Where an ice shelf is melting. Upon reflection, about one half of the ocean will have a salinity less than the average.
Which biome has a salinity of .005 or less?
Freshwater has a salinity of .005 percent or less.
What ocean has the most salt?
the surface of the ocean, like the top. where the water is less dense. less dense, less salinity, more dense, more salinity,think of it that way, that's how i do it.
Which biome has a salinity of 005 percent or less?
freshwater
Give three areas in the ocean where salinity may be less than average?
Around the mouth of rivers and glaciers, or where an ice shelf is melting.
How does the rain affect the salinity of the ocean?
It makes it less salty because rain isn't salty.
What is the salinity of the Pacific ocean?
Salinity is the saltiness or dissolved salt content of a body of water. The average ocean salinity is 35 ppt. This number varies between about 32 and 37 ppt. Rainfall, evaporation, river runoff, and ice formation cause the variations. For example, the Black Sea is so diluted by river runoff, its average salinity is only 16 ppt. Freshwater salinity is usually less than 0.5 ppt. Water between 0.5 ppt and 17 ppt is called brackish. Estuaries, where fresh river water meets salty ocean water, are examples of brackish waters. Saline waters from inland seas can have a composition that differs from that of the ocean.
List the reasons for variations in salinity in the various oceans?
Salinity can vary because of water temperature, rivers emptying into the ocean and mixing with ocean water, ice forming or melting, evaporation and precipitation. I think temperature is the biggest reason.
How does salinity affect the density of the ocean water?
Dissolving salts in water increases the density slightly. Ocean waters have an average density about 2.5% greater than fresh water. The Dead Sea has a much higher density, somewhere roughly near 20% greater than fresh water due to its 30% salinity level.
What is the average precipitation of the benthic zone?
please answer!!!! The neritic zone is the very shallow area near the coast- that's all I can help with for now!!!!Answerplease answer!!!! The neritic zone is the very shallow area near the coast- that's all I can help with for now!!!!
