Question

a mountain of ice floating in the sea..

Answer 1

it is a ice berg

An iceberg is a large piece of freshwater ice that has broken off from a snow-formed glacier or ice shelf and is floating in open water.

Because the density of pure ice is about 920 kg/m³, and that of sea water about 1025 kg/m³, typically only one-tenth of the volume of an iceberg is above water. The shape of the remainder under the water can be difficult to surmise from looking at what is visible above the surface. This has led to the expression "tip of the iceberg", generally applied to a problem or difficulty, meaning that the visible trouble is only a small manifestation of a larger problem.

Icebergs generally range from 1 to 75 meters (about 3 to 250 feet) above sea level and weigh 100,000 to 200,000 metric tonnes (about 110,000-220,000 short tons). The tallest known iceberg in the North Atlantic was 168 meters (about 551 feet) above sea level, making it the height of a 55-story building. Despite their size, the icebergs of Newfoundland move an average of 17 kilometers (about 10 miles) a day. These icebergs originate from the glaciers of western Greenland, and may have an interior temperature of -15 to -20°C (5 to -4 °F).

Though usually confined by winds and currents to move close to the coast, the largest icebergs recorded are calved, or broken off from, the Ross Ice Shelf of Antarctica. Iceberg B-15, photographed by satellite in 2000, measured 295km (183 miles) long and 37km (23 miles) wide, with a surface area of 11,000 km² (4,250 square miles). The mass was estimated around 3,000,000,000 metric tonnes.

When an iceberg melts, it makes a fizzing sound called "Bergie Seltzer." This sound is made when compressed air bubbles trapped in the iceberg pop. The bubbles come from air trapped in snow layers that later become glacial ice.

Ice campers who camp on top of flat or hollowed icebergs are known as icebergers.
