What are 2 factors that can affect chemical composition of seawater?
Temperature, salinity and pressure affect the density of seawater.
What are the factors controlling salinity of ocean water?
Controlling Factors of Salinity:
- (1) Evaporation:
- (2) Precipitation is inversely related to salinity e.g., higher the precipitation, lower the salinity and vice versa.
- (3) Influx of river water:
- (4) Atmospheric pressure and wind direction:
- (5) Circulation of oceanic water:
What are three factors that affect the chemical composition of seawater?
The physical and chemical properties of seawater vary according to latitude, depth, nearness to land, and input of fresh water. Approximately 3.5 percent of seawater is composed of dissolved compounds, while the other 96.5 percent is pure water.
How do you overcome salinity problems?
How To Reduce Soil Salinity?
- Increase drainage for better flushing (to remove salts from the ground surface).
- Plant salt-tolerant crops to manage economic risks and to ensure land cover.
- Remove salt crystals from the surface mechanically.
- Restore the balance via chemical amendments (e.g., gypsum or sulfuric acid).
What happens to salinity as temperature increases?
With increasing temperature, salinity decreases….and conversely, with decreasing temperature, salinity increases.
Why does salinity decrease with temperature?
Increases in temperatures of surrounding entities like ice and an increase in precipitation adds fresh water into the sea, which lower salinity. Seawater with lower salinity is lighter in density and won’t sink as much as denser water. This process changes ocean currents.
What does high salinity mean?
High salinity makes water denser. This is because there is more salt packed into the water. High temperature makes water less dense. As water gets warmer, its molecules spread out, so it becomes less dense. As it gets colder, it becomes denser. Most chemicals get denser when they turn from a liquid to a solid,…
What causes ocean salinity to increase?
Evaporation is the process that contributes to increased salinity of the ocean. The process of evaporation removes water and hence as the water level decreases due to the rise of water vapor into the atmosphere, more salt is left behind in lesser water, thus increasing the salinity.
What is salinity in biology?
Salinity refers to the amount of dissolved salts in water. Since salts conduct electricity, electro conductivity is used to measure the concentration of dissolved salts. Salinity influences the ecology of a water-body and determines what biological processes occur.
What is the salinity of the Atlantic Ocean?
On average, the Atlantic is the saltiest major ocean; surface water salinity in the open ocean ranges from 33 to 37 parts per thousand (3.3–3.7%) by mass and varies with latitude and season.
