Fun facts about Antarctica
At the southernmost point of the world, you find Antarctica a giant mass of ice that’s its own continent. You, may not know much about the continent, so why not read on?
There’ s a lake that runs blood red in Antarctica.
As though someone has cut into the ice, the properly named Blood Falls come out over the Taylor Glacier. The water is extremely high in iron and salt, and when it comes into contact with the air, it shows the special red color against the pure white surroundings. The water here is three times saltier than ocean water, and therefore, too salty to become ice.
Antarctica has its own treaty (条约).
Because the environment of Antarctica is so delicate and unique, there is a treaty saying that only peaceful research can be done there. In 1959, 12 countries signed this treaty, with the number now sitting at 53. This also makes it certain that Antarctica doesn’t end up being caught in an international conflict, and that the continent is only used for scientific purposes and sensible traveling. The treaty prevents army and nuclear activities, and also mineral mining.
There is a unique phenomenon in Antarctica called diamond dust.
While there are low levels of precipitation (降水) in Antarctica, that doesn’t mean the air is clear of nature’s beauty! The air is so cold there that moisture (水汽) can condense while air-borne. This results in ice falling to the ground. The sun’s light will cause the ice to shine, creating a shining shower called diamond dust. It happens when the skies are clear, known as clear-sky precipitation.
