Snowslide is a term used to describe a sudden and massive movement of snow down a slope. However, there are several other words that can be used to describe this natural occurrence. One such word is avalanche, which is commonly used to describe a large-scale snowslide that poses a threat to human life and property. Another synonym for snowslide is a snowdrift, which is a mass of snow that accumulates in a particular location over a period of time. Other words that can be used to describe a snowslide include snow flow, snow slurry, and snow cascade, all of which describe the movement of snow down a slope or hill.
