How does cold weather effect the density of the oceans?

Answer 1

the general answer to your question is, cold weather makes oceans more dense.

pure water is most dense at 4C or about 39F. although ocean water is not straight h2o, it is very diverse and complicated, it will act similarly. since most ocean water is above 4C, colder weather will cool it down towards 4C, making it more dense. as it gets colder than 4C, it will become less dense, that is evidenced by the fact that the top layer will freeze, and it will be liquid underneath, that is because frozen water is lense dense (lighter than liquid water) its even much more complicated, because as i said, seawater is a complicated thing

Answer 2

As the water at the surface of the ocean cools in winter it becomes more dense and begins to sink (around 4˚C). The sinking of the now more dense water displaces the water below it creating a downward current. Toward the bottom of the ocean (or below the thermocline) the water will then become even colder 2-3˚C. At this temperature water begins to expand and will move towards the surface until it warms again (back to around 4˚C) and sinks. This process allows for mixing of the ocean. During warm weather, the warmer water heated by the sun tends to stay at the surface of the ocean and there is little vertical mixing.

Answer 3

in the ocean there is salt, when when the ocean gets colder the salt in the water actually flows slower making or a thicker denser feel and look

Answer 4

Molecules are always moving in everything. When something heats up the molecules move faster and are more spread out (less dense). When something is colder the molecules move slow and are close together, making it more dense.

Answer 5

the colder water cant hold as much dissolved salt so the salt would sink to bottom & form thicker layer against methane burps & such.
density? colder water is denser but if it cant hold as much salt? i cant do the math .

Answer 6

when it's colder, things (including oceans) get more dense.
