What best describes the change in salinity in an estuary at low tide (as water leaves the area)?
At low tide, as water leaves the estuary, salinity typically increases. This occurs because the volume of freshwater from rivers decreases, reducing the dilution effect of freshwater on the seawater. Consequently, the concentration of salt in the remaining water becomes higher, leading to elevated salinity levels. Additionally, evaporation may also contribute to this increase in salinity.

Sediment that leaves heavy minerals in places where the river slows down called?
estuary
Is salinity the highest in the hot dry area?
Yes, salinity is higher in dry, hot areas because the high evaporation rate leaves behind salts dissolved in the 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.
Why is salinity higher in areas with more ice?
because ocean water leaves salt behind when it freezes
How does evaporation affect salinity near the equator?
Evaporation near the equator increases the salinity of the ocean water because it removes fresh water and leaves behind the salts, making the water more saline. This can lead to higher salinity levels in tropical regions compared to other areas of the ocean.
How does the cryosphere and hydrosphere affect ocean salinity?
The cryosphere, which includes ice and snow, influences ocean salinity primarily through processes like melting and freezing. When ice melts, it releases freshwater into the ocean, decreasing salinity in the surrounding waters. Conversely, when seawater freezes, it leaves behind salt, increasing salinity in the remaining liquid water. Additionally, changes in precipitation and runoff from snowmelt can further affect salinity levels in coastal areas.
Does heavy evaporation increase or decrease salinity?
Heavy evaporation increases salinity because as water evaporates, it leaves behind dissolved salts, minerals, and other substances, which results in a higher concentration of salt in the remaining water.
Suppose the salinity of surface ocean water is high in a particular place what might you infer about the area's rates of evaporation?
If the salinity of surface ocean water is high in a particular place, it suggests that there is high evaporation rates in that area. As water evaporates, it leaves behind salt, increasing the salinity of the remaining water.
How does evaporation affects salinity?
Evaporation leaves salt behind. So as ocean water decreases, the percentage of salt increases, increasing salinity. As evaporation increases, rainfall also increases, thus it decreasing the salinity of ocean water.
Is burning of leaves physical change or chemical change?
Burning leaves would be a chemical change because once the leaves are burnt, you can't turn the ashes back into leaves.
What D describes trees that shed their leaves in autumn?
Deciduous
Does high evaporation rates in subtropics cause the surface ocean water to have a lower than average salinity?
No, high evaporation rates in subtropical regions typically lead to higher salinity in surface ocean waters. As water evaporates, it leaves behind salts and other dissolved substances, concentrating them in the remaining water. This results in elevated salinity levels, contrary to the idea of lower-than-average salinity.
