What else can I help you with?
What can you determine by using the temperature and salinity of ocean water oceanographers can determine what?
Oceanographers can determine ocean currents, density variations, and the distribution of marine organisms by using the temperature and salinity of ocean water. These properties influence the movement of water masses and the distribution of marine life in different parts of the ocean.
Which of the following causes the density of seawater to increase?
Seawater denssity will increase as salinity increases. A less significant increase can result from temperature variations (colder is denser until freezing starts). Even smaller changes would occur with depth as the seawater is slightly compressible. As density is measured as mass/unit volume local gravity does not enter into the process.
What is the density in seawater determined by?
Seawater's density varies by temperature and salinity. I.e., cold water is more dense than warm water, and water with a higher salinity (more dissolved salt) is less dense than water with a lower salinity.
How do you Summarize the properties (temperature salinity density) you would expect to find at different depths of the ocean?
In general, as you descend deeper into the ocean: temperature decreases, salinity tends to increase due to evaporation and freezing processes, and density rises due to the combined effects of temperature and salinity variations. These properties play a crucial role in shaping the ocean's circulation patterns and influencing marine life distribution.
What is salinity and how does salinity change with depth?
Salinity refers to the concentration of salt in water. Salinity typically increases with depth in oceans due to the processes of evaporation and freezing which leave behind salt in the water, as well as the mixing of water masses within the ocean.
Salinity variations in the open ocean normally range from 33 percent to?
Salinity variations in the open ocean typically range from about 33 parts per thousand (ppt) to 37 ppt. These variations can be influenced by factors such as evaporation, precipitation, river runoff, and ocean currents. In some regions, such as coastal areas or estuaries, salinity can fluctuate more dramatically due to localized conditions. Overall, the average salinity of seawater is approximately 35 ppt.
Salinity in open-ocean zone?
Salinity is the saltiness or dissolved salt content of a body of water.The average ocean salinity is 35 ppt. This number varies between about 32 and 37 ppt. Rainfall, evaporation, river runoff, and ice formation cause the variations. For example, the Black Sea is so diluted by river runoff, its average salinity is only 16 ppt.
What is the sea water salinity level around Greece?
The seawater salinity level around Greece typically ranges between 36 to 39 parts per thousand (ppt), which is slightly higher than the global average of about 35 ppt. This elevated salinity is influenced by factors such as evaporation, limited freshwater input, and the Mediterranean Sea's unique hydrography. Variations in salinity can occur due to seasonal changes, freshwater runoff, and local climatic conditions.
What do you call deep ocean circulation driven largely by variations in water temperature and salinity?
thermohaline
How does salinity cause a current to flow?
Salinity differences can create a current through a process called thermohaline circulation. This occurs when variations in water density due to differences in temperature and salinity cause water to move in response to gravity. In regions where water becomes denser due to higher salinity, it sinks and creates a flow towards areas of lower salinity, resulting in a current.
What happens during which mountains and variations occur?
Mountains and variations occur due to the land moving and changing gradually over time. Mountains and variations can effect the way that land sits and moves.
Salinity variations in the open ocean normally range from 33 parts per thousand to?
38 parts per thousand
What is the average salinity range for a coral reef?
The average salinity range for a coral reef typically falls between 30 to 40 parts per thousand (ppt). This salinity level is crucial for coral health, as corals are sensitive to changes in salinity. Variations outside this range can negatively impact coral growth and overall reef ecosystems. Thus, stable salinity is essential for maintaining the biodiversity that coral reefs support.
How does salinity change in an estuary?
Salinity in an estuary changes due to the mixing of freshwater from rivers and saltwater from the ocean. This creates a gradient where salinity varies with depth and distance from the river mouth, often leading to a stratified environment. Factors such as tidal fluctuations, river discharge, and seasonal variations influence these salinity levels, resulting in dynamic and diverse habitats. As a result, estuaries support unique ecosystems adapted to varying salinity conditions.
How do variations occur?
During evolution, chromosomal cariation in structure cannot occur due to
Where does salinity mostly occur?
It mostly occurs in Australia due to salty rivers or salty water
How variations occur in a population?
because the fountain is magic
