Where does most dilution of seawater occur?
Most dilution of seawater occurs at the surface due to processes such as precipitation, river inflow, and melting ice. This leads to a lower salinity at the surface compared to deeper ocean layers. Ocean currents can also mix and dilute seawater over large distances.
Which process contributes the most to the salts found in seawater?
The process that contributes the most to the salts found in seawater is weathering and erosion of rocks on land. As rainwater, which is slightly acidic, flows over rocks, it dissolves minerals and releases ions such as sodium, chloride, magnesium, and calcium into rivers. These ions eventually reach the oceans, where they accumulate over time, contributing to the salinity of seawater. Additionally, hydrothermal vents and volcanic activity also contribute some salts, but the majority comes from terrestrial sources.
When a systime has reached chemical equilibrium the concentrations of the reactants and products?
When a system reaches chemical equilibrium, the concentrations of reactants and products remain constant over time. The rate of the forward and reverse reactions becomes equal, and there is no further change in the amounts of reactants and products.
How salinity and temperature affects the seawater?
Salinity and temperature are conservative properties of seawater that directly affect the density of seawater. This is an extremely important property because it in turn directly affects upwelling and downwelling of oceans and some major oceanic currents. This is because if a denser body of water is sitting on top of a less dense body of water, the denser part of the water column will turn over (sink) to get to a more stable water column state. This leads to water mixing of nutrients and oxygen for organisms living in the water column. Typically the saltier the water, the higher the density and also the colder the water, the higher the density. So because of this, cold and salty water (Antarctic and Arctic) are the most dense bodies of water and typically stay towards the bottom of the ocean floor.
How do you explain the peculiarity on the salinity of sea water and similarly for the hardness of water?
Although the question is very badly written and hence not easy to work out the meaning of, I assume the peculiarity referred to is that seawater and hard waters are similar. If so, there is no peculiarity at all; it is what we expect. Both contain higher than normal levels of dissolved salts, so there salinity is roughly the same. In the case of seawater, it is sodium chloride for the most part, but for hard water it is normally calcium salts.
Why does salinity remain constant over time?
Salinity remains relatively constant over time because there is a balance between the influx of fresh water (from sources like rivers and precipitation) and the evaporation of water from the ocean. Any changes in salinity are usually localized and temporary, as the ocean has a large volume and slow mixing processes.
What level of salinity will plants not grow?
Plants grow in seawater e.g. mangroves. There are other flowering plants that grow in shallow seawater. Seawater is about 3.5 % salt. Water needs to be over 3.5 % salinity before plants cannot grow.

Why is believed that seawater has always been salty?
Seawater becomes salty through the process of erosion and weathering of rocks on land, which releases minerals like sodium and chloride that eventually make their way into the ocean. Over time, this accumulation of salts has led to the overall salinity of seawater.
The average salinity of the world ocean?
Salinity of the ocean water is defined as the dissolved salt content in a body of water. The salinity of the ocean is 3.5%, the salinity increases as you approach the equator and decreases as you approach the poles.
Does the gravitational constant change over time or is it a constant value?
The gravitational constant, denoted as G, is considered to be a constant value in physics. It is a fundamental constant that is believed to remain the same over time and across the universe.
How could desalination affect the salinity of ocean?
Desalination does not directly affect the salinity of the ocean, as the vast volume of seawater is not significantly impacted by the relatively small amount of water that is desalinated. However, the brine left over from desalination processes, if not properly managed, can increase salinity in the immediate area where it is discharged, potentially affecting local marine ecosystems.
What two properties determine the density of sea water?
Temperature and Salinity. Both are important although temperature has a much greater effect than salinity on seawater density.
What is genetic equilibrium and how does it describe a population in which the allele frequencies remain constant and do not change over time?
Genetic equilibrium is a state in which the allele frequencies in a population remain constant and do not change over time. This means that the population is not evolving and there is no change in the genetic makeup of the population.
What three traits appear at an early age and remain constant over time?
extraversion, neuroticism and psychoticism
When a systime has reached chemical equilibrium the concentrations of the reactants and products?
When a system reaches chemical equilibrium, the concentrations of reactants and products remain constant over time. The rate of the forward and reverse reactions becomes equal, and there is no further change in the amounts of reactants and products.
Are wages a fixed or variable cost?
wages are variable cost reason being is that wages are being used over and over again and does not remain constant.
