Realisation of the day:

WHEN ICE MELTS THE WATER LEVEL DOESNT CHANGE!!!!!! OMG!!!!!

Darn it. I always thought the water level will rise.......=P Gah. Gah. =P

EXPLANATION :
Floating Ice that Melts Doesn't Raise the Sea Level

Why doesn't floating ice that melts increase the sea level? By definition, anything that floats displaces its own weight in water. In other words, if the floating ice melts, the resulting water would be exactly equal to the amount of water displaced while the ice was floating. The sea level, therefore, already includes the total amount of water in all floating ice.

You can easily verify this in your own kitchen, just make a glass of ice water (to my fellow Americans with our love of ice: be sure none of the ice is grounded on the bottom of the glass!), mark the water level in the glass, then go node for a while until all the ice melts. The water level will not have changed.

And why does the sea level increases during global warming? Coz its the ICE CAPS that arent floating in d water that melts, that's why!!!!=P
