How are temperature and salinity related in a thermohaline circulation pattern quizlet?
As the salinity increases, the density increases; as the temperature increases, the density decreases.
How does temperature and salinity affect the flow of water?
Since warmer water thus can hold more salt and other molecules than cold water; it can have a higher salinity. To relate this to ocean currents, the higher the salinity of ocean water, the more dense it becomes. When the salinity is high enough, the water will sink, starting a convection current.
What drives the thermohaline circulation pattern?
The thermohaline circulation is mainly driven by the formation of deep water masses in the North Atlantic and the Southern Ocean caused by differences in temperature and salinity of the water.
How does thermohaline circulation affect global temperature?
Thermohaline circulation plays an important role in supplying heat to the polar regions. Therefore, it influences the rate of sea ice formation near the poles, which in turn affects other aspects of the climate system (such as the albedo, and thus solar heating, at high latitudes).
What is thermohaline circulation quizlet?
Thermohaline circulation is a worldwide current system in which the warmer, fresher water moves along the surface while the colder, saltier water moves beneath it.
What is thermohaline circulation and how does it work?
Thermohaline circulation describes the movement of ocean currents due to differences in temperature and salinity in different regions of water. Temperature and salinity change the density of water, resulting in the water to move accordingly.
How does temperature affect salinity?
With increasing temperature, salinity decreases….and conversely, with decreasing temperature, salinity increases.
How does water temperature and salinity drive global ocean circulation?
These deep-ocean currents are driven by differences in the water's density, which is controlled by temperature (thermo) and salinity (haline). This process is known as thermohaline circulation. In the Earth's polar regions ocean water gets very cold, forming sea ice.
How does salinity affect ocean currents?
As the seawater gets saltier, its density increases, and it starts to sink. Surface water is pulled in to replace the sinking water, which in turn eventually becomes cold and salty enough to sink. This initiates the deep-ocean currents driving the global conveyer belt.
Could the rising ocean temperature disturb the thermohaline circulation?
Global warming could potentially cause a thermohaline circulation shutdown and subsequent regional cooling, but because Earth will continue to warm as a result of greenhouse gas emissions, it would not produce another Ice Age.
How does salinity affect thermohaline circulation?
Great Salinity Anomaly This lower density deters the normal process of sinking at high latitudes that supports thermohaline circulation, which makes it harder for the northern movement of warm water from the equator.
What process affect the distribution of temperature salinity and density of the surface layer waters?
Since seawater density depends mainly on temperature and salinity (section 6.3), this circulation is referred to as thermohaline circulation . The main processes that increase seawater density are cooling, evaporation, and ice formation.
What does the thermohaline circulation depend on quizlet?
Movement of ocean water caused by density difference brought about by variations in temperature and salinity.
How do temperature and salinity affect deepwater currents?
Remember that temperature and salinity also affect density. Lower temperatures and ? salinity increase the density of water, and more dense water will sink beneath less dense water. deep water currents form as a result of these differences.
How is ocean temperature and salinity related quizlet?
How does temperature affect salinity? As temperature increases, the space between water molecules increases—also known as density, which therefore decreases.
How do the salinity and temperature in the ocean vary?
Temperatures range from -2° C to 28° C in most cases, but are hotter near hydrothermal vents or closer to land. Salinity is usually 35 ppt (parts per thousand), but can range from 28-41 ppt and is highest in the northern Red Sea.
How do temperature salinity and density affect ocean structure?
Dense water sinks below less dense water. This is the principle that drives the deep ocean currents that circulate around the world. A combination of high salinity and low temperature near the surface makes seawater dense enough to sink into the deep ocean and flow along the bottom of the basins.
How does temperature and salinity affect the formation of deep currents?
As the seawater gets saltier, its density increases, and it starts to sink. Surface water is pulled in to replace the sinking water, which in turn eventually becomes cold and salty enough to sink. This initiates the deep-ocean currents driving the global conveyer belt.
How do temperature and salinity affect seawater density?
The density of water increases as the salinity increases. The density of seawater (salinity greater than 24.7) increases as temperature decreases at all temperatures above the freezing point. The density of seawater is increased by increasing pressure.
How are the temperature salinity and density related?
The density of water increases as the salinity increases. The density of seawater (salinity greater than 24.7) increases as temperature decreases at all temperatures above the freezing point.
What is the relationship between temperature salinity and density in the ocean?
The warmer the water, the more space it takes up, and the lower its density. When comparing two samples of water with the same salinity, or mass, the water sample with the higher temperature will have a greater volume, and it will therefore be less dense.
What can affect thermohaline circulation?
As opposed to wind-driven currents and tides (which are due to the gravity of moon and sun), the thermohaline circulation (Fig. 1) is that part of the ocean circulation which is driven by density differences. Sea water density depends on temperature and salinity, hence the name thermo-haline.
How do temperature and salinity affect deepwater currents as temperatures and salinity levels of water increase the water rises to the surface where?
Remember that temperature and salinity also affect density. Lower temperatures and ? salinity increase the density of water, and more dense water will sink beneath less dense water. deep water currents form as a result of these differences.
How do temperature and salinity affect seawater density quizlet?
How are the properties of seawater interrelated? Temperature influences density. For pure water, density increases as the temperature decreases. Salinity influences this relationship in that the saltier the water, the denser it becomes.
How are temperature salinity and density related quizlet?
How is density affected by temperature and salinity? Increasing salinity also increases the density of sea water. Less dense water floats on top of more dense water. Given two layers of water with the same salinity, the warmer water will float on top of the colder water.
How are temperature and salinity related?
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.
What happens to salinity as temperature increases?
With increasing temperature, salinity decreases….and conversely, with decreasing temperature, salinity increases.
How are density salinity and temperature related in each layer of ocean water?
Temperature and salinity both affect density. Low-density water tends to be warmer and less saline, while high-density water is generally cooler and more saline. 4. Pressure also affects seawater density, but only in the deepest parts of the ocean.
How does temperature affect ocean currents?
Warming temperatures result in weakened currents. If the water at the poles is not as cold and dense, it simply won't be able to circulate as well. Additionally, the melting of the Greenland continental ice sheet is pouring freshwater into the salty ocean, again altering the density of the water masses.
How does density temperature and salinity related?
The density of water increases as the salinity increases. The density of seawater (salinity greater than 24.7) increases as temperature decreases at all temperatures above the freezing point.
