The Antarctic ice sheet contains an estimated 7.0 million cubic miles of ice. If the entire ice sheet melted, how many feet would the average global sea level rise? The density of ice is about 0.90 g/cm^3. The density of water is about 1.0 g/cm^3. The total area of the world's oceans is about 134 million square miles.
Well, If one considers the ice to be floating, then like magic when it melts, the water level does not rise. Think on that.
Fill a glass with ice to the above the brim. Add water to the absolute rim of the glass. Now let the ice melt and see if the melted water overflows. (It doesn't).
Why is this? Think about archemedes principle and the density of ice.
Now your question: this melting ice sheet is an urban myth. The increase of sea levels will not result from floating ice, but rather from land ice /snow, or ice that is resting on the bottom of the Arctic ocean (which there is little of that, mostly around Canada shore). look at the words and pictures here; http://express.howstuffworks.com/ask-mb-ice-melt.htm
they show a picture of floating ice! Your exeriment with the ice water will debunk that.
However, they are right about greenland, and glaciers melting, and land ice, and ice resting on the bottom of the Arctic Ocean.
Many folks in this world live by the idea that if you say something enough, people will believe it, and cite it as references in a paper.
Few actually do the experiment.
To find out how many feet the average global sea level would rise if the entire Antarctic ice sheet melted, we need to calculate the volume of the ice sheet and then convert it into the corresponding sea level rise.
Step 1: Calculating the volume of the ice sheet
The volume of the ice sheet can be calculated by multiplying its estimated size (7.0 million cubic miles) by a conversion factor to convert cubic miles to cubic centimeters.
1 cubic mile = 1.609344 × 10^15 cubic centimeters
So, the volume of the ice sheet in cubic centimeters can be calculated as follows:
Volume of ice sheet = 7.0 million cubic miles × 1.609344 × 10^15 cubic centimeters
Step 2: Converting the volume of the ice sheet to mass
Now that we have the volume of the ice sheet in cubic centimeters, we can calculate its mass. To do this, we multiply the volume by the density of ice.
Mass of ice sheet = Volume of ice sheet × Density of ice
Step 3: Converting the mass of the ice sheet to the mass of water
Next, we need to convert the mass of the ice sheet to the equivalent mass of water, since we want to determine the sea level rise. To do this, we divide the mass of the ice sheet by the density of water.
Mass of water = Mass of ice sheet ÷ Density of water
Step 4: Converting the mass of water to volume
To determine the volume of water needed to raise the global sea level, we divide the mass of water by the density of water.
Volume of water = Mass of water ÷ Density of water
Step 5: Converting the volume of water to sea level rise
Finally, we divide the volume of water by the total area of the world's oceans to calculate the sea level rise in feet.
Sea level rise = Volume of water ÷ Total area of world's oceans
Now that we have the steps, we can calculate the answer using the provided data.
