i was thinking the other day if the ice melted would the water level really rise????????????
i mean ice takes up more space than water, so if the ice melted,there would a lower water level as water takes less space!!
for examle, fill a glass with ice then put water in it so it full to the top, when all the ice melts the water level will go down!!!
what do you all think?
-
NO !
it will Rise
Just think of the millions apon million of toons of water that will release.
also people in say ......London should Worry !
as Great Britian is riseing in the north of Scotland and Sinking in the South of England.
which means if PreZ Bush gets his way on the Environment, well let me say the UK will have the world first underwater Capital !
;)

yeah, but you gotta remember the ice wont be there, what happens when you fill a bottle, then freeze it, the top blows off, as the ice takes more room up!!!!!!
yeah i heard about the south sinking, and north rising, cos of the ice age, and it compressed the north, but i dont care i live in a 130ft boat!!!!1

True but you have to under stand that even though Ice has Mass.
The properies of Water is that its the only substance known to us that the solid floats on its own liquid (this propertie is on of the reasons why the ice caps are important in the state of the sea levels).
as the ice level melt the quanity of liquid H20 will increase even though Water is effectivly part of the oceans and seas as ice, the effect on Sea levels will be Accumulative.
for example
if sea level is at exactlly 0 m
and we have a high level of ice at our poles
then if the ice caps start to melt
we will have an increase the sea level
due to the fact that there is now less water being trapped at the poles.

A lot of the ice is not sitting in the water though, fill up you glass, then put a piece of ice in your hand, let it melt, then add it to your full galss, and you got yourself some spillage.

The part you\'re missing is this: When you put a piece of ice in water, the ice floats. Thus, a large part of it\'s mass is actually above the waterline, and does not displace any of the water below it. The same thing happens with huge ice flows at the poles of our planet. If the ice started melting, it would release more water into the ocean, raising the sea level. The ice that was previously supported above the waterline would sink, and displace just as much water as before. Therefore, a net increase in liquid water, and a higher sea level.

thanks peeps.
Damn why have i got a headake now :(

hmmm well actuallysomeone else said it to me, thats why i thought about it, il have to tell him these awnsers, i ccouldnt think of any

You should put an ice-pack on your head. :hat:

Awwwwwwoooooooollllllll now i have a cold chil headake :( ;)
Damn it.... you people this is the one place were i come to get way from work (i.e. the Environment) ;)

think of it like this... fill a glass full of water..freeze it..then let it defrost, same amount of water..minus the small, small amount that will evaporate.

Dude, you just shattered your glass in the freezer.

1) Not all water is trapped as ice in the Oceans, there are large amounts of ice in antartica (over solid rock), on mountains, and in glaciers around the world.
2) Because Ice is less dense than water, it floats on water. However, so much is exposed that a half water-half ice glass, becomes a 3/4\'s full glass of water (thereby raising the water).
3) As you change the global temperature, even just a three degree rise in average water temperature will cause expansion. While a few degrees will make a negligible volume difference to a glass of water, when you talk about the entire world, you will be talking millions of units of volume in expansion.

heh if all Ice melted all of little old Iceland wouls sink. And I would turn into AquaMan

not true..if you catch it in time..or just use a plastic cup. :)

I didn\'t explain the reason even ICE on water doesn\'t work that way.
Imagine a small tub of water. Now imagine you have two cups of water. Freeze one cup of water. If you added the liquid water to the cup, it would rise by the displacement of 1 cup of water. If you add the frozen cup of water, it will only displace about 2/3rds of a cup of water, and 1/3rd of a cup of displacement will remain above the water. When that ice melts, however, the third of the ice that wasn\'t displacing any water will be part of the water, and the waterlevel will rise accordingly.
