Lake Natron is a salt and soda lake in northern Tanzania. It is quite a shallow lake, and temperature at the lake is frequently above 40°C. The lake has a lot of soda which makes living creatures die. When living creatures reach the lake, all organs are corroded and all moisture in their bodies evaporates just in a second. But flamingos can live in there because they have soda resistance. The lake looks red because it has a high pH, so only red plankton can live in high pH.
These frozen bubbles are under Alberta’s Lake Abraham in Canada. They look like jewels but are very dangerous because it’s actually frozen pockets of methane. Methane bubbles form in bodies of water when dead organic matter (leaves and animals) falls into the water and sinks to the bottom. And then, the bacteria munches on the matter and poops out methane. Methane is a highly flammable gas, so be careful with fire as it can explode.
