Does freezing water also rise sea levels?

Question

Since water's maximum density of 1 gram/cm3 is at 3.98 Celsius, and people have said that warming ice and melting it will rise sea levels, due to the density, won't freezing water a lot also rise sea levels?

I'm also kind of confused on why sea levels rise if Archimedes' principle applies.

And Moose said that freezing water will be deposited on land. Why not floating in water?

Answer 1

Freezing water on the earth actually lowers sea levels (takes water out of the oceans and deposits it on land in the form of snow and glaciers)...

Answer 2

moose was referring to an "ice age". during an ice age, glacial ice piles up on the land, sometime a mile thick. this water came from the ocean, so the ocean literally had less water then, so its level dropped. Anyway the effects of an ice age have nothing to do with water density.

the original claim of sea water rising was based on a reverse ice age, however these people forgot that most polar ice is already displacing water, and according to Archimedes the water level does not change because of melting. So now they justify the previous predictions of disaster by saying the density of the ocean will change, thus causing the rise in sea levels. If the ocean warms enough to change in density, it will also increase the vapor pressure and water will evaporate faster. This will put more water in the air and on land so it will counteract the effect of rising by removing water from the ocean.

At some point the criers of disaster will say oops, and admit they really don't know how global warming will affect the ocean level.

Answer 3

Think of the decreasing density (and expansion of the ice) on the surface of the seas and oceans....now think on the Archimedes Law, that states that no two different physical bodies can occupy the same space in this dimension or universe....
The conslusion, is that, despite there would be more frozen water, this ice will have more space t FLOAT, and not occupy the volume arlready occupied by ocean water....It wil occupy the air above the icebergs.....
matter of basic logics...
Ice Floats....dense water at 4 degrees celsius (maximum density) does not....

Answer 4

Ice is less dense than water. If large volumes of water are frozen, the ice formed will float on the remaining water. There is a net loss of liquid water, thus the sea levels would (and often have been) lower.

Answer 5

sea levels go down in ice ages and more land is exposed as the free water has been "held" in ice and glaciers etc (so there is literally less water in the oceans etc)

Answer 6

the biggest part of all the ice on this planet (by far!!) is on top of (the LAND of) the south pole. If it melts it's ADDED to the water in the seas. Therefore: sea-levels rise when the (south)polar-ice (and the other land-ice as well (like glaciers)) melts.
