With the exception of water flowing from hydrothermal vents in the seafloor, the water temperature in these lowest parts of the ocean can be as low as 2o to 4o Celsius.
The Andes, at 4,300 miles long, are the world's longest mountain range above water. The undersea Mid-Oceanic Ridge, which runs between all continents and measures roughly 40,390 miles in length, is the world's longest mountain range.
Coastal towns and tiny island nations are put at risk by rising seas, which exacerbate coastal flooding and storm surge, making catastrophic weather events even more dangerous. Greenland's ice sheet loss is a major predictor of future sea level rise; if it melts completely, global sea levels might rise by 20 feet.
Sea water cannot be consumed, but sea ice can. Fresh sea ice, on the other hand, should not be consumed since it still contains small pockets of saltwater trapped between the ice crystals. The salt seeps out of the ice as it ages, and the ice becomes fresh enough to melt and consume, according to the NSIDC.
Water covers around 71 percent of the earth's surface, while the seas hold 96.5 percent of all the water on the planet
Around 20 million tonnes of gold can be found in ocean waters all around the world, A littre of water would have around 13 billionths of a gramme of gold in it.There is currently no cost-effective method for extracting gold from sea water that is economical
The Pacific Ocean is the world's largest and deepest ocean basin. The Pacific Ocean basin, which covers over 63 million square miles and contains more than half of the world's free water, is by far the largest of the world's ocean basins.
The majority of living forms began their evolution in maritime environments. Oceans cover over 90% of the planet's surface area and supply 90% of the world's living space. More over 200,000 marine species have been identified, with another two million or so yet to be discovered.
