How 'bout this weather?

never heard of that, but if it is true then would it be enough to counteract the ice turning to water? I'm sorry maybe I'm just thick, but everything I've learned about "displacement" says that something with HIGHER volume is going to displace MORE water then something of lesser volume, how is that effect going to be completely reversed simply because its applied to such a massive scale?

Yes ice has a higher volume, but that extra volume is the part of the iceburg that sticks out of the water, so it doesn't displace any water.
 
I think you need to retake your 8th grade science. Water doesn't shrink then magically expand again. Water just expands as it is frozen.
 
i know you are but what am i?
 
i was merely giving the same advice that you gave to me when you thought i had not learned something from a class.
 
Because you obviously didn't, but nothing i say will get through to you, so i'll just step away from this one before i get an aneurysm.
 
you didnt even bother to look to see that you were wrong?
 
With increasing average global temperature, the water in the oceans expands in volume, and additional water enters them which had previously been locked up on land in glaciers, for example, the Greenland and the Antarctic ice sheets. An increase of 1.5 to 4.5 °C is estimated to lead to an increase of 15 to 95 cm (IPCC 2001).

This is the reason why the melting of the ice in Antartica and Greenland would cause massive global flooding. Trillions of cubic tons of water dumped into the world's oceans combined with the expanded volume of the already present water. Hence, displacement.
 
Upon further research because my interests were piqued I came to the realization that icebergs float because water expands when it freezes. I'm sure this is something I knew for a week or two in middle school, but it's obviously something I forgot as it's "the exception."

lol Antor. That's the reason I remembered it. My 9th grade physical science teacher said "water's an exception." So it stuck :)

smalls: go back to school.
Makelith: play nice :D
 
ok if you want to get technical about things water does have a negative thermal expansion between 0-4 which is why it is considered the exception. but in general hot= greater volume cold= less. either way makelith is still horribly wrong. so if anything you should be telling him to go back to school.
 
Back because this caught my eye.

Which is what everyone has said, unless i'm misunderstanding what you are trying to say. It is the exception.

No one argued the general rule of things. Everyone knows heat makes the volume go up and coldness makes the volume go down.

Go away.
 
you said water doesn't shrink then expand. then i say it does. then you agree. are you missing the contradiction?
 
I believe the point Smalls was trying to make is that the volumen of H20 does decrease as its temperature decreases until it reaches the freezing point, then it expands. The volume of water vapor > volume of steam > volume of water < volume of ice

yes this is what i was saying. but not just vapor > water. i was more talking about hot water > room temp > cold < water 4-0 degrees. water is only the exception between 4-0 degrees above 4 degrees C it follows the same rule as everything else
