Three major factors influence salinity (salt concentration) in Pacific Ocean waters: precipitation, evaporation and winds. Hereof, what are the factors affecting the temperature of the sea water?
Generally spoken, sea water will heat up due to solar radiation, geothermal energy and metabolic processes of sea life. Sea water will cool down by radiation of heat, melting ice and evaporation. Also, sea currents can carry hotter or cooler water from elsewhere.
Secondly, what are the two factors that control the concentration of salts in seawater? Evaporation and temperature are the two main factors that control the concentration of salts in seawater.
Just so, how does temperature affect salinity of ocean water?
As temperature increases, the space between water molecules increases—also known as density, which therefore decreases. As density increases, the amount of salts in the water—also known as salinity, increases. Various events can contribute to change in the density of seawater.
What is temperature of ocean water?
The average temperature of the ocean surface waters is about 17 degrees Celsius (62.6 degrees Fahrenheit).

What are the 4 factors that affect temperature?
Although many factors combine to influence weather, the four main ones are solar radiation, the amount of which changes with Earth's tilt, orbital distance from the sun and latitude, temperature, air pressure and the abundance of water. What causes warm ocean water?
The main source of ocean heat is sunlight. Additionally, clouds, water vapor, and greenhouse gases emit heat that they have absorbed, and some of that heat energy enters the ocean. Waves, tides, and currents constantly mix the ocean, moving heat from warmer to cooler latitudes and to deeper levels. Which ocean has highest temperature?
Indian Ocean
Which sea obtains highest annual range of temperature?
The average annual range of temperature is about 12 degrees Celsius. The highest annual range of temperature is recorded in the North Atlantic Ocean. Where does the salt in oceans come from?
Salt in the sea, or ocean salinity, is mainly caused by rain washing mineral ions from the land into water. Carbon dioxide in the air dissolves into rainwater, making it slightly acidic. When rain falls, it weathers rocks, releasing mineral salts that separate into ions. What is the average salinity of ocean water?
35 parts per thousand
Is salinity higher in warm or cold water?
Salinity, Density, and Temperature When the water molecules of the ocean become heated, they expand. Since warmer water thus can hold more salt and other molecules than cold water; it can have a higher salinity. Does salinity increase with temperature?
As temperature increases, the space between water molecules increases—also known as density, which therefore decreases. As density increases, the amount of salts in the water—also known as salinity, increases. Various events can contribute to change in the density of seawater. Which ocean has the highest salinity?
Pacific Ocean
How does salinity affect climate?
The density of seawater is a function of salinity and temperature, Lagerloef explained. Saltier water is heavier and will sink deeper in the ocean, where it joins currents that circulate water around the globe. Stable salt densities in the oceans keep the earth's climate in balance, scientists believe. Why is salinity important in water?
Salinity levels are important for two reasons. First, along with temperature, they directly affect seawater density (salty water is denser than freshwater) and therefore the circulation of ocean currents from the tropics to the poles. Measuring salinity is one way to probe the water cycle in greater detail. Does ocean salinity increase over time?
Records showed that the saltier parts of the ocean increased salinity -- or their salt content -- by 4 percent in the 50 years between 1950 and 2000. If the climate warms by an additional 2 or 3 degrees, the researchers project that the water cycle will turn over more quickly, intensifying by almost 25 percent. Does temperature and salinity affect water density?
There are two main factors that make ocean water more or less dense than about 1027 kg/m3: the temperature of the water and the salinity of the water. Ocean water gets more dense as temperature goes down. So, the colder the water, the more dense it is. Increasing salinity also increases the density of sea water. What increases salinity?
Evaporation of ocean water and formation of sea ice both increase the salinity of the ocean. 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. What increases salinity in an estuary?
Salinity levels in estuaries typically decline in the spring when snowmelt and rain increase the freshwater flow from streams and groundwater. Salinity levels usually rise during the summer when higher temperatures increase levels of evaporation in the estuary. What happens when water's salinity increases?
There are parts of the ocean where hardly any rain falls but warm dry winds cause lots of evaporation. This evaporation removes water – when water vapour rises into the atmosphere, it leaves the salt behind, so the salinity of the seawater increases. This causes the seawater to become denser. What controls the salinity of deep water?
Evaporation of ocean water and formation of sea ice both increase the salinity of the ocean. 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. Which three factors are most important in determining the composition of ocean water?
Temperature, salinity, and density are the group of factors are most important in determining the composition of ocean water. What causes Halocline?
In oceanography, a halocline (from Greek hals, halos 'salt' and klinein 'to slope') is a subtype of chemocline caused by a strong, vertical salinity gradient within a body of water. In such regions, the vertical stratification is due to surface waters being warmer than deep waters and the halocline is destabilizing. Does salinity increase with depth?
At higher lattitudes, salinity tends to be less at the surface and increases with increasing depth. Actually, what changes with depth is the density of the water. The deeper you go, the denser the water becomes. Density, in turn is mainly affected by two factors - salinty and temperature. Why is ocean salinity so high in the subtropical gyres?
A combination of increasing direct evaporation over the regions with increasing remote evaporation over nearby E-P maxima is believed to be the main driver in increasing salinity of the subtropical oceans, suggesting an intensification of the global water cycle over decadal time scales. Why does salinity increase with depth?
At very great depth, salinity increases again because the water near the ocean bottom originates from polar regions where it sinks during the winter; freezing during the process increases its salinity.
