Is it wrong to use "sliding"? [closed]
When I was growing up sliding was what happened when someone was pushed down a hill without the apparatus to ride on. Sledding was going down the hill with your toboggan or otherwise instrument of potential snow hill destruction.
I do not think either way is inaccurate as there are always regional differences in the way individuals refer to items and actions.
Sledding requires a sled (or as some responders have called it, a sledge. I think "sledge" is British; I know Americans call it a sled.)
I went sledding as a kid, in western Washington state. What matters is not how deep the snow is, but how wet it is, and whether it is compacted or re-frozen so as to have a relatively hard surface. Such compacted snow occurs often in wetter zones, whereas parts that are dry in winter (Colorado, Minnesota, etc) are more likely to have "fluffy" snow, which is too soft for sledding, because the narrowness of the sled's runners concentrates the rider's weight on a few square inches. Driven-on roads (after a few inches of snow) which then get some sun to barely melt the surface, make ideal sled runs. You could even "slide" on your shoes, standing up, on such icy snow.
But you can "slide" on any kind of snow with anything you can sit on (a plastic disk, a piece of cardboard, etc) which distibutes your weight so as to not dig into the snow—provided the hill is steep enough.
