Which is correct covered by snow or covered with snow?
That's a really difficult a question. In British English either is equally correct though they can have subtle differenced in meaning which I am finding difficulty explaining. Of course you have the third variant which is "Covered 'in' snow".I'm sure that somebody else can describe it in technical terms. But my understanding as a natural English speaker is....Covered 'by' snow kind of infers that this action has recently occurred.e.g. The parked car was covered by snow.Covered 'with' snow kind of infers that the object has not recently been covered.e.g. The parked car was covered with snow.Covered 'in' snow is kind of descriptive.e.g. The parked car was covered in snow.You know what I don't think it matters, choose one and use it,
Why sand is thrown on the roads covered with snow?
Impurities in water will lower the freezing point of water. Salt on the roads will melt the ice, making the roads less slippery. The icy water now freezes at perhaps -5º instead of 0ºC. When there is salt, freezing of water (i.e. ice formation) will take place at temperatures lower than 0ºC .However there is a limit on lowering of the freezing point of water using salt. When temperatures are as low as -20º or -30ºC, putting salt on icy roads will no longer work. At these temperatures you now need to add a different chemical, Sodium Acetate. The salt also provides some traction in the form of increased friction between ice, packed snow and the tires of the cars or feet of those walking.
