Do rivers freeze?

ANSWER

Rivers can and do freeze. While water moving requires a lower temperature they still can freeze. Something to note is that even the Niagara Falls have frozen as recently as 2019.

Large rivers do not freeze "through out" because, Water, ice, and snow are good insulators and poor conductors of heat. The portions of a lake or river that are exposed to the cold winter air will freeze into ice and this ice insulates the water below from further rapid freezing.
