Why does a ship float lower in the water when it goes from sea water into a freshwater estuary?
Saltwater is denser than freshwater:When salt is dissolved in water, as it is in ocean water, that dissolved salt adds to the mass of the water and makes the water denser than it would be without salt.
Because objects float better on a dense surface, they float better on salt water than fresh water. The denser the salt water, the easier it is for objects to float on top of it.

What else can I help you with?
What are the 3 major water biomes?
Freshwater Biomes, Estuary Biomes, and Marine Biomes
Which coastal region is where seawater and freshwater mix?
The coastal region where seawater and freshwater mix is called an estuary. The mixed water inside the estuary is called brackish.
Is estuary a freshwater ecosystem?
Its considered freshwater and salt water because they both meet together
What is a rich zone where a freshwater stream mixes with ocean water?
Estuary
Will ice float in salt water?
Yes, ice will still float in salt water. However, the presence of the salt increases the water's density, requiring a slightly lower temperature for the ice to float compared to freshwater.
Would salinity increase or decrease in an estuary during spring floods?
Salinity would decrease in an estuary during spring floods due to the influx of freshwater from increased runoff and precipitation. The dilution effect of the additional freshwater entering the estuary would lower the overall salinity levels.
Why does freshwater float on saltwater?
Freshwater is less dense than saltwater because it has a lower concentration of dissolved salts. This difference in density causes freshwater to float on top of saltwater, creating distinct layers when they meet.
Why would egg float in saltwater and and not freshwater?
Eggs can float in saltwater because the high density of saltwater makes the overall density of the egg lower than that of the water, causing it to float. In freshwater, the egg is denser than the less dense water and therefore sinks.
What type of water is most likely to float on the surface of the ocean?
Freshwater is less dense than seawater because it has a lower salinity, so it is more likely to float on the surface of the ocean. This is why rivers flowing into the ocean form distinct layers of freshwater on top of the saltwater.
What best describes the change in salinity in an estuary at high tide (as water enters the area)?
At high tide, salinity in an estuary typically decreases as freshwater from rivers and streams flows into the area, diluting the saltwater from the ocean. This influx of freshwater can create a stratification effect, where less dense freshwater overlays the denser saltwater. Consequently, the overall salinity levels within the estuary are lower during high tide compared to low tide when more saltwater is dominant.
The area where a river meets the ocean and contains a mixture of freshwater and saltwater?
Estuaries
Where does a river and ocean met and contains a mixture of of freshwater and saltwater?
This area of water is known as an estuary.
