In the Arctic, the main contribution to sea level rise is from the Greenland ice sheet. Sea ice is melting at an alarming rate, but because the sea ice already sits in the oceans, this does not contribute to sea level rise. Mountain glaciers are also trickling into the oceans quickly, but their mass is much less than that of Greenland, so we won't use them in this estimate - even though the worldwide melt rate of mountain glaciers is higher than that of Greenland. All the same, we'll approximate that all of the sea level rise in the Arctic is coming from Greenland.
Greenland is losing about 250 million tons of ice each year (267 +/- 38 Gton/yr to be exact), and has a total ice mass of 2.3 x 10^15 tons. Thus, the fraction of ice Greenland is losing each year is 1 x 10^(-7), or 100 billionths of its total mass. Note that this number is the *net* loss - it includes both the losses from calving icebergs and surface melt, and the gains from snowfall on the interior.
Antarctica is less clear because we have fewer measurements about the snowfall accumulation on the interior. Many different projections of the mass balance have come up with different values - the study I will use found that the mass balance is -5 to +85 million tons of ice per year. The total mass of Antarctica is 2.2 x 10^16 tons, so Antarctica is doing something in the range of losing 0.2 billionths of its mass to gaining 4 billionths of its mass each year. Again, these estimates are Antarctica's net mass balance - losses from calving and gains from snowfall.
We have observed about 3-4 millimeters per year of sea level rise, averaged over the entire twentieth century. Most of the observed sea level rise to date is actually due to thermal expansion of sea water - hotter water takes up more space. The colder water coming in from the melting ice sheets is insignificant compared to the huge volumes of warmer ocean water that already exist.

A tire risks melting when making contact with surfaces over 250 degrees.
It melts the snow and ice making the sidewalk safer. It does pit and mar the sidewalk surface over time, making replacement necessary.
Melting a candy bar is a physical change because it is just changing form, not changing the chemical makeup. (If it isn't making a new material, it is not a chemical change)
The Polar Regions are defined by the Antarctic and Arctic Circles. The Antarctic Circle is at 66 degrees 32 minutes S latitude. The Arctic Circle is at 66 degrees 32 minutes N latitude.
Melting of gold for jewellery making is a physical change as no new substance is formed after melting. Changes in state or phase are physical changes.
The Arctic Circle and Antarctica are on opposite ends of the earth. Traveling north from the Arctic Circle would take you to the North Pole in the Arctic sea ice, then you'd have to travel south, where you'd cross the Arctic Circle once again. Continuing your southern journey, you'd cross the Antarctic Circle before reaching Antarctica the continent, where you'd pass over the South Pole. Then you'd have to travel north again. You'd cross the Antarctic Circle before making a full circle of the earth, again reaching the Arctic Circle.
There May have been some native peoples living on the coast, but Antarctica is a frozen desert. unlike the Canadian arctic, there is no lakes or rivers in Antarctica, there fore there is no fishing.
well they do helping animals and shoving snow and making house's
Antarctica is the iciest and driest continent, making it an icy desert.
I am not entirely sure I understand the question, but I believe the answer is yet. The darker the chocolate is, the higher the percentage of pure cocoa (making it taste less sweet and more bitter). The more cocoa that is in chocolate, the easier it will be to burn during the melting process.
Antarctica is, indeed, a continent, making up 10% of the Earth's surface.
there functions for melting metals and making horse shoes
temperature? :S
Antarctica, ok make it into a world wilderness park. Nobody cares.
Antarctica is a frozen land mass. It hardly, if ever rains in Antarctica making it the worlds driest dessert.
Green house gases created by melting and making it(melting plastic). The waste produced after use. (rubbish)
It's very cold and can be windy at times. With the heating of the temperatures. Ice has been melting making land more scarce. Temoeratures can go low for some temps., and is very cold like below 30 degrees.
