What are three areas in the ocean where salinity may be less than average?
Where a major river enters. Where a large glacier enters. Where an ice shelf is melting. Upon reflection, about one half of the ocean will have a salinity less than the average.
List three factors that affect salinity in the ocean and three factors that affect ocean temperatures. Explain how each factor affects salinity or temperatures?
Three factors are evaporation and freezing of sea water.
What are the three factors that from deep currents?
The three factors that form deep ocean currents are temperature, salinity, and density. These factors influence the movement of water masses in the ocean, creating currents that can circulate for thousands of kilometers.
Which three factors are most important in determining the composition of ocean water?
temperature,salinity,and density
What are three ways that density of ocean can increase?
here are 3 ways... 1) temperature going down 2) the salinity of the water 3) ice blocks...
What are three things that effect currents?
Three factors that affect ocean currents are wind patterns, the Earth’s rotation (Coriolis effect), and differences in water temperature and salinity. Wind drives surface currents, while the Coriolis effect alters their direction based on the hemisphere. Additionally, variations in temperature and salinity create density differences in water, influencing deeper currents in the ocean. Together, these elements shape the complex movement of ocean waters.
What are three ways in which the ocean water varies?
Ocean water varies in temperature, salinity, and depth. Temperature changes with latitude and depth, affecting marine ecosystems and currents. Salinity, influenced by factors like evaporation, precipitation, and freshwater influx, affects water density and circulation patterns. Additionally, the depth of the ocean impacts pressure and light penetration, further influencing marine life and chemical processes.
What are three areas where plate boundaries may be located?
Middle of the ocean floor, around the edges of the continents, and within the continents.
How is ocean water different from fresh water?
Ocean water has a higher salinity level due to the presence of dissolved salts, while fresh water has a lower salinity level. Ocean water is also denser and can support different types of marine life compared to fresh water ecosystems. Additionally, ocean water covers a much larger percentage of the Earth's surface compared to fresh water.
What are 3 processes that control salinity explain how each changes salinity?
Three processes that control salinity are evaporation, precipitation, and freshwater inflow. Evaporation increases salinity as water vapor leaves the surface, concentrating the dissolved salts in the remaining water. Precipitation decreases salinity by adding freshwater, which dilutes the concentration of salts in the water. Freshwater inflow from rivers or melting ice also reduces salinity by introducing lower-salinity water into saltier bodies, balancing the overall salinity levels.
What are the three ways that oceans are different from each other?
Ocean water is separated into different types: what oceanographers call "water masses", based on the meteorologists' term "air masses." Water masses are defined by their temperature and salinity balance. These water masses acquire their temperature/salinity balance at the surface and then sink down into the deeper levels of the ocean while maintaining that balance. Since this relationship is slow to degrade, it can be used to track large sections of water through the ocean from a common source.
How deep is a ocean floor if a sound wave is sent out by a ship and the reflected wave is detected six seconds later?
Water travels at about 1560 m/s* in salt water. Since the sound wave took three seconds to reach the floor, that's 4680 meters or 15,354 feet 4 inches. That's just a little deeper than the ocean-wide average (12,430 ft.) *the exact rate depends on pressure, temperature, and salinity.
