How Do Waterfalls Freeze?

 
nature-waterfalls_frozen

Water turns to ice when its molecules move slowly enough to form rigid bonds. Normally, the molecules in the waterfall move under the influence of both the flow and thermal agitation.

But if it gets cold enough, the heat effect becomes so low that not even the waterfall’s motion can stop ice forming, gradually at first but then ever more rapidly.

  1. How is it that #16 &23 have not been arrested for indecent exposure. Bring back the boys with hip pants showing the top of their undies. At least they’re pretty much covered.

  2. I change into clean clothes, mix my make-up and hair before i go to shop at Walmart. Just think of all the effort and time I’v been wasting!
