Snowfalls occur when atmospheric conditions allow water vapor to freeze and fall to the ground as snowflakes. This process typically happens when temperatures are below freezing, causing the moisture in the air to crystallize. Snowflakes can vary in size and shape, depending on the temperature and humidity levels during their formation. Snowfalls can significantly impact the environment and daily life. They can blanket landscapes, creating beautiful winter scenes, but also lead to challenges such as reduced visibility and hazardous travel conditions. Areas that experience regular snowfalls, like the Rocky Mountains or Northeast United States, often have infrastructure in place to manage snow removal and ensure safety.
