It is determined by the density of seawater.

Factors influencing sea temperature:
1. Latitude: The temperature is different if the solar radiation obtained at different latitudes is different. The distribution of global seawater temperature decreases from low-latitude to high-latitude areas.
2. Ocean current: In the sea area at the same latitude, the temperature of the warm current through the sea water is higher, and the temperature of the cold current through the sea water is low.
3. Season: high sea temperature in summer and low sea temperature in winter.
4. Depth: The surface seawater decreases significantly with the increase of depth, the change is obvious within 1000 meters, the change is small from 1000 meters to 2000 meters, and the low temperature is maintained at 2000 meters all year round.
Distribution of sea water temperature
The horizontal distribution of surface seawater.
Same sea area, different seasons – high water temperature in summer, low water temperature in winter.
In the same season, the water temperature is high in different sea areas - low latitudes and low water temperatures in high latitudes.
Same latitude, different sea areas – warm currents pass through the sea area with high water temperatures.
Vertical changes in sea temperature.
Since solar radiation first reaches the surface of the seawater, the temperature of the seawater varies with depth. From the surface layer to the deep layer, the water temperature gradually decreases, and the water below the surface layer changes very little, and the deep sea water below 1,000 meters often remains cold.
The regulating effect of seawater on atmospheric temperature.
The ocean has a large area, a large amount of water, and a large heat capacity, so the change in sea temperature is much smaller than that of land temperature. As a result, the temperature over the ocean changes more slowly than over the land, so the sea water plays a regulating role in atmospheric temperature.

The reasons why the drop in temperature affects the seawater are as follows:
1. The density difference decreases: after the surface seawater temperature drops, the density increases, and the density of the deep cold water is larger, but with the increase of the density of the surface seawater, the density difference between the deep cold base and the water gradually decreases, so that the deep cold water has been inhibited to a certain extent.
2. Hydrodynamic effect: When the surface seawater becomes colder, it is more likely to be stirred up by wind and waves than deep cold water, and has higher speed and energy, which also has an impact on hydrodynamics, which may cause in some cases to hinder or delay the rise of the deep cold current to the surface.

Hehe, that's an interesting question.
It should be discussed in a categorical manner, and the law of change of sea temperature is different in different seasons and at different latitudes.
In high latitudes, the sea surface temperature is generally low, and the sea temperature below is relatively high, such as the Antarctic and Arctic regions; At the equator and at lower latitudes, the temperature of the sea surface is highest as it absorbs the radiant heat of the sun, and the further down it goes, the lower it gets.
Of course, there are many factors that affect the temperature of the seawater, such as the activity of submarine volcanoes, which can cause the water to be hot in the deep seabed. In addition, the movement of ocean currents can also cause large differences in sea temperature, such as the Mexican Gulf Stream, the North Atlantic Current, the Kuroshio Current, the Tsushima Current, the East Australian Current, the Mozambique Current, ......Cold snaps such as the Kuril Current, the California Snap in the North Pacific, the Peruvian Snap in the South Pacific, the Canary Snap in the North Atlantic, the Benguela Snap in the South Atlantic, the Western Australian Snap in the South Indian Ocean, and so on.
-
For example, if the sea surface is frozen, the temperature is about 0 degrees Celsius, but the temperature on the seabed is generally 4 degrees Celsius (the density is the highest).
-
The sea water temperature gradually decreases with the increase of depth (about 1°-2 for every 1000 meters), and reaches 2°--1 at 3000-4000 meters. At this point, the temperature is basically the same.
Good luck with your studies o(o!
-
Yes! However, below the depth of 2,000 meters, the temperature is constant at about 4 degrees Celsius.
-
The temperature distribution of sea water decreases in a gradient from sea level to the bottom of the sea.
-
Generally speaking, yes, the ** of temperature is generally thermal energy. But if there is a volcano at the bottom of the sea, it's a different story.

Question 1: What are the factors that affect the temperature and salinity distribution of sea water Temperature: latitudinal position, ocean current salinity:
Latitude location, degree of closure of the sea area, whether there is freshwater river injection and other questions 2: what are the factors affecting seawater corrosion The chloride ion content in seawater is very large, so the anodic polarization block of most metals in seawater is very small, and the corrosion rate is quite high; Epoxy conditions such as waves, splashes, and flow velocities can promote the cathodic depolarization of oxygen and promote metal corrosion. The conductivity of seawater is very large, so not only the activity of corrosive microbatteries is large, but also the activity of macrobatteries.
When different metals meet in seawater, galvanic corrosion is susceptible. Factors that affect seawater corrosion include salt content, dissolved oxygen, temperature, waves, flow velocity, and marine organisms. There are a large number of salts mainly sodium chloride dissolved in seawater, and the salt content of seawater is expressed in salinity.
Salinity refers to the total mass of dissolved solid salts in 1000g of seawater.
Question 3: How does the terrain affect the temperature of the sea Hello landlord:
The sea temperature decreases with the increase of depth, so when the seabed topography is high, the distance from the sea level to the seabed is smaller, and the sea water temperature is correspondingly higher, question 4: What is the sea water temperature The sea water temperature is the same as the land, and it is also different from place to place, but there is one point, compared with the adjacent land, the sea temperature is higher than the land in winter, and the opposite is true in summer, does it help you.
The vast majority of the ocean is blue, and if there is more suspended matter in the seawater, or other reasons, the color of the sea is no longer blue. For example, China's Yellow Sea, which is the estuary of the Yellow River in ancient times, has a large amount of sediment carried by the Yellow River into the sea, and the blue sea water is "dyed yellow". Although the Yellow River now pours into the Bohai Sea, the northern part of the Yellow Sea is connected to the Bohai Sea through the Bohai Strait, and it has to withstand the water injected by the Huai River, Guan River and other rivers, so the sea surface still has a light yellow color. >>>More
The conditions for seawater to freeze are not the same as for freshwater to freeze. Anyone who lives by the sea has experienced that when the cold air comes in early winter, the shallow ponds on land quickly freeze into a thin layer of ice; In the depths of winter, the rivers freeze, but the sea is still choppy, with undulating waves. Only when cold waves break out frequently and the air is at a low temperature for a long time will the sea water freeze. >>>More
Seawater is the "home" of salt, and seawater contains various salts, about 90% of which are sodium chloride, that is, table salt. In addition, it also contains magnesium chloride, magnesium sulfate, magnesium carbonate and other salts containing potassium, iodine, sodium, bromine and other elements. Where does so much salt come from in the sea? >>>More
Seawater contains a large number of salts and a variety of elements, many of which are needed by the human body. However, the concentration of various substances in seawater is too high, far exceeding the drinking water health standard, if a large amount of drinking, it will lead to excessive entry of certain elements into the human body, affecting the normal physiological function of the human body, and serious poisoning. >>>More
