Earth's ocean is very important to us; it covers almost three-quarters of our planet. If all the ice in glaciers and ice sheets melted, the sea level would rise by about 80 meters (262 ft), about the height of a 26-story building.90% of an iceberg is under water--ships beware!f sea level should rise by 3 meters (10 feet), many of the World's coastal cities, like Venice, London, New Orleans, and New York, would be under water.
