The term BIT OF FALLING SNOW can be solved by the crossword solution FLAKE, which is a five-letter word. A FLAKE is a single crystal of snow, which is a form of precipitation made up of frozen water droplets. Snowflakes are unique in that no two snowflakes are alike, and they come in a variety of shapes and sizes. Snowflakes are formed when water vapor in the atmosphere condenses and freezes into ice crystals. As the snowflake falls, it collects more water vapor, which causes it to grow and take on its unique shape.
