What is the salinity of the Indian ocean?
Surface water salinity ranges from 32 to 37 parts per 1000
Which usually had greater salinity deep or surface currents?
Deep ocean currents typically have greater salinity compared to surface currents. This is primarily due to factors such as evaporation in warmer regions and the formation of sea ice, which increases the concentration of salts in the water. Additionally, deep currents are often sourced from colder, saltier water masses that have sunk and are less affected by precipitation and runoff that can dilute surface salinity.
What is the salinity level of the Indian ocean?
Surface water salinity ranges from 32 to 37 parts per 1000
Suppose the salinity of surface ocean water is high in a particular place what might you infer about the area's rates of evaporation?
If the salinity of surface ocean water is high in a particular place, it suggests that there is high evaporation rates in that area. As water evaporates, it leaves behind salt, increasing the salinity of the remaining water.
What cause surface ocean water to have a higher salt content?
The main reasons for higher salt content in surface ocean water are evaporation and formation of sea ice. As water evaporates, salt is left behind, causing an increase in salinity. In regions where sea ice forms, the salt is expelled, further increasing the salinity of the remaining water.
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 temperature in the ocean at Antarctica?
Ocean water off the Antarctic coast is between 32F degrees and about 27F degrees, based on the salinity of the water. It's always warmer in the ocean water than it is above the surface of the water.
What moves water parallel to Earth's surface?
Winds and ocean currents move water parallel to Earth's surface. Winds can create surface currents through friction with the ocean's surface, while ocean currents are driven by a combination of factors such as wind, temperature, salinity, and the Earth's rotation.
The measure of the amount of solids dissolved in ocean water is what?
salinity
In the subtropics the saltiest water is generally at the surface, why?
What causes low salinity in the oceans at high latitudes?In subtropical latitudes, high surface evaporation creates high salinity near the sea surface. In subpolar latitudes, high precipitation creates low salinity near the sea surface. As these waters flow into the ocean interior, they create layers of high and low salinity.
How is ocean water salinity different in tropical areas than at the north an south poles?
Surface water slainity is higher in tropical regions.
The salinity of the ocean?
You could increase the salinity of the ocean by adding salt or removing water (ie: by evaporation).
