Algae bloom causes the lake to turn green, and the algae gets it's nutrient from treated sewage and runoffs with dissolved fertilizers, which contains high nitrogen and phosphorous.
The greenish blue color of a lake can be due to the presence of algae or phytoplankton in the water. These microscopic organisms contain pigments that give the water a greenish hue. Additionally, the reflection of the sky and surrounding vegetation can also contribute to the blue color of the water.
The blue appearance of a lake is the result of the reflection of a blue sky on the water's surface. A jar of water indoors does not have a blue reflection from the sky and therefore does not have a blue color.
When you look into an ocean or a lake, the water looks like it's blue. But, up close, water isn't really blue. It's only blue when you look at it in big groups, (like an ocean or a lake, a pond etc.), because the sky is blue, so the color of the sky makes a blue reflection on the water, making it look blue. So, on a map, if you drew water as clear, nobody would be able to tell there was anything there at all! So, water on a map is drawn blue instead.
There is no definitive count of blue water lakes in the world, as the term "blue water lake" can refer to various bodies of water known for their striking blue color due to factors like depth, purity, and mineral content. Notable examples include Lake Tahoe in the United States, Lake Louise in Canada, and the Blue Lake in New Zealand. Each region has its own unique lakes that may be considered blue, but the total number is not officially documented.
The phrase "deep blue sea" means any deep water - if you have ever seen really deep ocean or lake water, you know that it is a really deep blue, almost black, color.
Blue Lake (Tikitapu) or Green Lake (Rotokakahi) near Rotorua.
the color blue on a map often shows a lake or an ocean = D
Deep deep blue if you mean the Crater Lake in Oregon.
Usually, algae (AL jee) -- tiny plants. Algae can grow on surface of the water or on rocks and other stuff on the bottom. Sometimes it's not the water that's green, but the lake bottom or stream bottom. In shallow areas, sunlight reflects off the algae growing on the bottom and makes the water look green. High concentrations of copper can also make water look green.
Pure water has a slight blue color to it. See the Web Links below for the explanation.Note that while water does have a slight bluish color, it is mostly transparent. This is because the molecule does not absorb any light in the visible region of the electromagnetic spectrum (no light that we can see).What most often gives water its color, for instance in a lake, river, or ocean, is not the color of the water itself, but rather the color of things in it, like plants or seaweed, sediment, or other substances. Also, reflection off the surface of the water often make the water take on the color of whatever is being reflected.
first of all, get a Pokemon that knows surf. then go to the lake, click on the water, and it will say "The water is a deep blue color... would you like to surf on it?" click "yes". Then it will say " ________ used Surf!" Then you'll be surfing on the water.
The Geneva conference was when a group of representatives from the us government game together to decide if the water in lake Geneva was either blue or greenish. Yes this is true and very stupid of the US. Aren't you glad we live here.
