If the ice covering Antarctica all melted, sea level would rise approximately
 A 0 feet B 4 feet C 20 feet D 200 feet
Explanation:

Detailed explanation-1: -The whole world will never be underwater. But our coastlines would be very different. If all the ice covering Antarctica, Greenland, and in mountain glaciers around the world were to melt, sea level would rise about 70 meters (230 feet). The ocean would cover all the coastal cities.

Detailed explanation-2: -If the Antarctic Ice Sheet melted entirely, it would raise global sea levels by around 200 feet (60 meters).

Detailed explanation-3: -If all the Antarctic ice melted it would raise the average sea level by about 70 m (230 feet) worldwide. This would change the map of the world as we know it as all coastlines would flood including the loss of all coastal cities in the world.

Detailed explanation-4: -At its thickest point the ice sheet is 4, 776 meters deep. It averages 2, 160 meters thick, making Antarctica the highest continent. This ice is 90 percent of all the world’s ice and 70 percent of all the world’s fresh water.

Detailed explanation-5: -Antarctica is losing ice mass (melting) at an average rate of about 150 billion tons per year, and Greenland is losing about 270 billion tons per year, adding to sea level rise.
