You are reading about which of the following areas in the ocean is likely to have the lowest salinity?. Here are the best content from the team C0 thuy son tnhp synthesized and compiled from many sources, see more in the category How To.
Ocean salinity [1]
There are many chemicals in seawater that make it salty. Most of them get there from rivers carrying chemicals dissolved out of rock and soil
Most seawater has about 35 g (7 teaspoons) of salt in every 1,000 g (about a litre) of water. This doesn’t sound very much, but it would take close to two 6 m shipping containers full of salt to make an Olympic-size swimming pool as salty as the sea.
Most of the ocean has a salinity of between 34 ppt and 36 ppt.. Some properties of water are changed by having salt in it:
Least salty sea [2]
– 7–8 grams salt per kilogram of water total number. The Baltic Sea in northern Europe has the lowest salinity of any sea, with an average salt concentration of 7–8 grams per kilogram of water (meaning that the water is 0.7–0.8% salt by weight)
There is significant variation in salinity between different parts of the Sea – with salt concentrations of between 10 and 32.7 g/kg in the Danish Straits and as low as 1 g/kg in the Gulf of Riga and the Gulf of Bothnia.. The least saline ocean, by comparison, is the Arctic Ocean, which has a typical salinity of 28–30 g/kg owing to the low rate of evaporation and meltwater from the ice-caps.

Ocean Salinity: Vertical & Horizontal Distribution of Ocean Salinity [4]
Refer to the latest edition of Physical Geography Hardcopy/PDF and Current Affairs for the most updated information on this topic.. – Salinity is the term used to define the total content of dissolved salts in sea water.
– It is usually expressed as parts per thousand or ppt.. – Salinity of 24.7 (24.7 o/oo) has been considered as the upper limit to demarcate ‘brackish water’.
– It also influences the composition and movement of the sea: water and the distribution of fish and other marine resources.. – The salinity of water in the surface layer of oceans depend mainly on evaporation and precipitation.
Which areas of the ocean have the lowest salinity and why? [5]
The lowest areas of salinity in an ocean are near where fresh water rivers empty into them. This is because the influx of fresh water creates an area of lower salinity compared to the remainder of the ocean.
In certain areas, the ocean can be close to 50 percent salt. Generally, the world’s oceans are between 32 and 35 percent salt.
Areas near the poles like the Arctic Ocean will have the lowest salinity. less dense, less salinity, more dense, more salinity,think of it that way, that’s how i do it.

[Solved] In which of the following regions the salinity of the oceans [7]
In which of the following regions the salinity of the oceans is found the highest?. – All waters in nature, whether rainwater or ocean water, contain dissolved mineral salts.
– It is calculated as the amount of salt (in gm) dissolved in 1,000 gm (1 kg) of seawater.. – It is usually expressed as parts per thousand (‰) or ppt.
– The salinity of 24.7ppt (parts per thousand) has been considered as the upper limit to demarcate ‘brackish water’.. – The highest salinity is found at Tropic of cancer and Tropic of Capricorn.
Factors, Horizontals and Vertical Distribution [8]
Salinity of Ocean Water – Factors, Horizontals and Vertical Distribution. Salinity refers to the total content of dissolved materials in water bodies
Salinity is a very important component that affects the physical and chemical properties of seawater. It determines the temperature of oceans and their surroundings, pressure, density, freezing point, insolation, evaporation, humidity, and oceanic currents flow
These are evaporation, rainfall, river water influx, ocean currents, atmospheric pressure, wind direction, and global warming. Though it is not equally distributed, it varies spatially and temporarily with oceans and seas
Ocean Exam #2 Flashcards [9]
Use LEFT and RIGHT arrow keys to navigate between flashcards;. List and describe 4 unique (special) properties of water.
-Solid, liquid, and gas on Earth’s surface: ice, water, fog, mist. -Unusual density, solid (ice) is less dense than liquid water
-Universal solvent, ability to dissolve many substances. Distinguish between covalent, ionic, and hydrogen bonding.
Pacific Ocean – Temperature, Salinity, Depth [10]
The oceans tend to be stratified, the principal factor being temperature; the bottom waters of the deep parts are intensely cold, with temperatures only slightly above freezing.. The surface zone, where temperature variations are perceptible, is between 330 and 1,000 feet (100 and 300 metres) thick
Ocean temperatures in the North Pacific tend to be higher than those in the South Pacific because the ratio of land to sea areas is larger in the Northern Hemisphere and because Antarctica and the Southern Ocean also influence water temperature.. The mean position of the thermal equator (the line on the Earth on which the highest average air temperatures are found; the line migrates latitudinally with the changing angular distance from the Equator of the Sun) in the Pacific, although it lies in the Northern Hemisphere, is nearer to the geographic equator than in the Atlantic and Indian oceans.
The deep zone, which contains about 80 percent of the ocean’s volume, has relatively stable temperature and salinity patterns; its average temperature is 38.3 °F (3.5 °C).. The salinity patterns of the surface waters of the Pacific are influenced largely by wind and by precipitation and evaporation patterns
Salinity In The Ocean Is Highest In Regions Where ________ Is High And ________ Is Low. [11]
Where in the oceans are the highest values of salinity found?. The highest salinity values occur in subtropical oceans where evaporation cause a buildup of salts in seawater.
Rivers weather down rocks and carry the minerals to the ocean. Which of the following factors would increase salinity in ocean water?
However these “salinity raising” factors are continually counterbalanced by processes that decrease salinity such as the continuous input of fresh water from rivers precipitation of rain and snow and melting of ice.. In what parts of the world’s oceans would you find the lowest salinity?

NASA Salinity: Seasons of Salinity [13]
You may experience long winters and mild summers or mild winters and hot/humid summers. Or perhaps you live in the tropics where temperatures are relatively constant but the seasons are “wet” and “dry.”
When it comes to salinity, tropical areas have the largest seasonal cycle of salinity. These patterns are unlike ocean temperature, where mid-latitude areas show the greatest variation throughout the year.
The primary ways that freshwater is removed from the ocean are evaporation or the freezing of seawater (i.e., making sea ice). On the other hand, freshwater is added to the ocean by precipitation, ice melt, and river runoff
Science of Sea Ice [14]
Sea ice is classified by stages of development that relate to thickness and age. A simple classification categorizes sea ice into two primary age groups: first-year or multiyear
The World Meteorological Organization (WMO) has defined the following categories:. – New ice is a technical term that refers to ice less than 10 centimeters (3.9 inches) thick.
Young ice is sometimes split into two subcategories, based on color:. – gray ice (10 to 15 centimeters, or 3.9 to 5.9 inches thick)
Saline Water and Salinity [15]
In your everyday life you are not involved much with saline water. You are concerned with freshwater to serve your life’s every need
Just look at the oceans and remember that oceans comprise about 97% of all water on, in, and above the Earth.. • Water Science School HOME • Surface Water topics • Water Properties topics • Water Quality topics •
In this case, the concentration is the amount (by weight) of salt in water, as expressed in “parts per million” (ppm). If water has a concentration of 10,000 ppm of dissolved salts, then one percent (10,000 divided by 1,000,000) of the weight of the water comes from dissolved salts.
