辽河上发现神秘旋转冰圈

A rotating ice circle over Liaohe River in Faku County of northeast China’s Liaoning Province has attracted hundreds of visitors since it was discovered this week.

辽河上发现一个旋转的冰圈,该地段位于中国辽宁省法库县,该奇观自本周被发现以来吸引了数百人前来观看。
The circle looks extremely round – like a watch surface from an aerial view – and is surrounded with frozen and solid ice as it rotates at a constant speed on the river.

It can still rotate with dozens of people standing1 on it, which has been tested out since becoming an attraction over the past few days.

According to scientific research, the phenomenon is sometimes seen in the North Pole, Scandinavia or Canada. The accelerated river flow can trigger rotational2 shear3 force, cutting the ice free and making it rotate slowly. The round shape is formed by friction4.
