The sea is blue because water, in large quantities, is blue. Also, when the light from the sun hits the water, it gets filtered so that redness is absorbed, allowing more of the blue color to be reflected.
Another reason why the sea appears blue is because it reflects the blue color of the sky. Little ocean particles serve as reflective devices, and because the sky surrounds the ocean, the water appears blue. The presence of plant life and algae can cause the sea to appear green, and it may even appear gray when the sky is cloudy. Water that contains large amounts of sediment may appear brown in color.Learn More
Accumulation is the part of the water cycle in which water gathers in large quantities such as rivers, lakes, oceans, glaciers, ice caps and aquifers, according to the U.S. Geological Survey. After water accumulates, it evaporates back into the atmosphere to start the water cycle over again. Accumulation occurs after water precipitates out of the sky.Full Answer >
Chloride, magnesium, sodium, sulfate, calcium, bicarbonate and potassium are the most abundant ions in sea water. These ions form the bulk of seawater, while oxygen and water form the remaining portion. The ionic makeup of seawater influences its salinity, saltiness, temperature and buoyancy.Full Answer >
Drinkable water can be obtained from seawater by removing salt through a distillation process. Distillation is a simple process that can be done on a small scale as a personal project or on a large scale as a desalination plant that provides drinking water for many. Despite its simplicity, desalination is an expensive process compared to getting drinking water from fresh water sources.Full Answer >
Unlike fresh water, which freezes at 32 degrees Fahrenheit, sea water freezes at 28.4 degrees Fahrenheit. The 3.6-degree difference in freezing temperature is due to the salt that is found in sea water, making it slightly more difficult to freeze.Full Answer >
