Why does applying rock salt to an icy sidewalk hasten the melting process?

Salt water melts at a lower temperature than pure water, so if the temperature is just slightly below freezing, near 32°F (or 0 °C), then putting salt on the ice will cause the ice to melt. However, if the temperature is really really cold (like -40 °C, which it turns out is the same as -40°C!), then putting salt won't make much difference.
Also, the rock salt used also does provide some traction as the rough salts makes the ice less slippery (in the same way that piece of gravel or sand would work).

Why do kids movies have depressing scenes?
A very good question! For generations certain topics were absoluteluy (Hands Off) for juvenile fare on movies and TV- suicide, fatal accidents involving children, Harrowing depressive plots, etc. One might add the television drama ( and it was deep drama indeed, aided by lugubrious sound effects and dark shadows making even the Great Outdoors a menacing landscape- LASSIE was almost entirely in this genre. I can"t recall any comic relief- say with monkeys escaping from a carnival or something, no way, Kids trapped in wells, accidents of all types- some extremely improbable, forest fires, even in one incarnation, a seismic volcano eruption ( the mystery of the shaking mountain).l Heavy stuff indeed. I hasten to add Lassie was a serial program here, not a movie ( movies were made on the themes) I hope this helps Depression is not entertaining. I agree with you there.

He did run cartoons * as did most live hosts of his type- such as Sandy Becker, Fred Scott and later, Soupy Sales. In later years , when on talk shows Mr. Keeshan tried to minimize the role of cartoons on his program, which is not true.
