does water freeze underwater?

Answer 1

Yes, it's possible. It's all about heat sources. Basically if there is a source that lacks heat energy causing water to freeze and it is stronger than the heat source warming water it will freeze.

Iused it in my Physics course and it was pretty helpful.

Answer 2

Ice floats, because when the water forms crystals, the water molecules spread apart a little bit and the density of it is less than that of liquid water. Also, water loses heat on the surface faster than it does in the depths. Even with a still bucket of water, there is cooling due to the wind passing over it and evaporation from the surface. Any individual water molecules that get cold enough to freeze will float to the surface, to the underside of the ice layer that is forming, and stick there and it grows thicker.

Think about this: if water froze from the bottom up, all the fish in shallow ponds would freeze, every winter, and die.

Answer 3

Good question! yeah you get me thinking, because if I remember it right, there were reports in some journals that the temperature underwater becomes lower as you get deeper, to the point of - degree Celsius. So if water freezes at zero degree, then how come water does not freeze underwater...hmm, there must be some fallacy in those "scientific discoveries".

Answer 4

H2O (water) expands when it freezes. The volume of H20 increases during the freezing process. The Ice becomes less dense than water. The Ice shelf then floats to the surface, while the water remains below. Example: a glass of ice water.

The formation of Ice in this manner, has allowed fish and other creatures to stay alive during winter-time. And, allow for a vast ecosystem at the North and South Poles. Another example is, Ice Fishing. Fishermen drill a hole in the Ice and are then able to fish. The fish are swimming in the waters below, while the fishermen are standing on the ice shelf above.

Answer 5

The depth of the ice is determined by the depth of the water body and the severity of the cold weather above. Water is at its densest when it is at 4 degree celcius. At this temperature, water will move to the bottom of the water body under the ice. It will not freeze. That is why Ice fishing is such a popular sport here in Canada! Got one Eh! Just kidding we dont actually talk like that!

Answer 6

You obviously don't live in a place that has harsh winters...on lakes and such, the top of the water freezes (the ice gets really thick...) and people do all sorts of stuff on the frozen water...snowmobile, car racing, and ice fishing...they drill a hole in the ice all the way to the open water, set a line to catch fish...hope this answers your question.

Answer 7

The top layer only freezes, not underwater

Answer 8

No. Only the top layer of the water freezes.

Answer 9

usually only the surface of water will freeze since thats going to be the coldest part. eventually the ice on the surface will get thicker as the temperature goes down but you wont find any ice chunks forming under the surface

Answer 10

Frozen water has less density than liquid water. As soon as ice crystals form it would float to the top. All ice forms on the top of the water here on Earth. I cant say about space.
