When ocean water freezes, the formation of ice causes the dissolved salts and other substances in the water to be expelled, increasing the concentration of salt in the surrounding liquid water. As a result, this saltier water becomes denser than the ice, which floats on top. Additionally, the freezing process itself leads to the exclusion of water molecules from the ice structure, further contributing to the density changes in the remaining liquid water. Thus, while ice is less dense than liquid water, the denser saline water remains below the ice layer.
What else can I help you with?
How does the uneven heating in the ocean cause convection currents?
it causes the difference in density, denser water flows to the less dense parts
As deep ocean water becomes colder it also becomes?
denser, due to the decrease in temperature causing the water molecules to contract and become more tightly packed. This increased density causes the cold water to sink to the bottom of the ocean, creating ocean currents as it displaces warmer, less dense water.
Which is denser ocean water or fresh water?
ocean water, because it is saltier.
Ocean crust dives below continental crust because?
Ocean crust is denser
What is denser fresh water or ocean water?
Sea water is denser, not only that, different oceans have different densities.
How is ocean stratified by density?
The ocean is stratified with denser layers below less dense layers.
Why does the ocean get denser near the poles?
because it is colder up there
How does water freezing at the poles helps create deep ocean currents?
When seawater freezes the salt is excluded from the ice and stays with the portion that remains liquid. The result is highly saline water called brine. The brine is denser than normal seawater and so sinks the the ocean floor, forming deep currents.
Why is ocean water denser than freshwater or pure water?
The water of the oceans is denser because of the high level of salt it contains.
What happens to ocean water as it becomes denser?
The water gets cooler
When ocean plates collide with continental plates what does the denser plate do?
sinks
What two processes cause an ocean to become a cloud?
The two processes that cause an ocean to become a cloud are evaporation and condensation. Evaporation occurs when water from the ocean's surface is heated by the sun and turns into water vapor. The water vapor then rises into the atmosphere, where it cools and condenses into clouds.
