The Blue Lake (37°50′S 140°46′E) in Mount Gambier is a large lake located in an extinct volcanic caldera. It is known as Waawor in the local Aboriginal language. ... Crater Lake, Oregon A caldera is a volcanic feature formed by the collapse of a volcano into itself. ... The Australian Aboriginal languages are a Australia, and the rest are descended linguistically from them. ...

During Summer (December to February) and the surrounding months, it appears to be a vibrant blue colour, returning to a more normal colour for Winter.

An explanation for this phenomenon is that carbon dioxide degasses from the magma and rises to surface, reacting with the limestone underneath the lake. This reaction dramatically increases the concentration of calcium dissolved in the water. The change in temperature of the calcium-rich lake causes the calcium to become supersaturated and precipitate out of the solution. Micro-crystallites of calcium carbonate scatter the blue wavelength of sunlight. Carbon dioxide is an atmospheric gas comprised of one carbon and two oxygen atoms. ... Magma is molten rock often located inside a magma chamber beneath the surface of the Earth. ... Limey shale overlaid by limestone. ... General Name, Symbol, Number calcium, Ca, 20 Chemical series alkaline earth metals Group, Period, Block 2, 4, s Appearance silvery white Atomic mass 40. ... HI JAMIE!!!!! In chemistry, the term supersaturation or oversaturation refers to a solution that contains more of the dissolved material than could be dissolved by the solvent under normal circumstances. ... Dissolving table salt in water In chemistry, a solution is a homogeneous mixture composed of one or more substances known as solutes that are dissolved in another substance known as a solvent. ... It has been suggested that crystallization processes be merged into this article or section. ... Calcium carbonate is a chemical compound, with chemical formula CaCO3. ... Rayleigh scattering causing a reddened sky at sunset Rayleigh scattering (named after Lord Rayleigh) is the scattering of light by particles much smaller than the wavelength of the light. ... The wavelength is the distance between repeating units of a wave pattern. ...

The Blue Lake supplies the town with drinking water, providing approximately 3,600 ML per year from its 36,000 ML store. Its average depth is 70 m. A megalitre (Ml or alternatively ML), also spelled megaliter, is one million (1,000,000) litres in the metric system. ...
