Winter snow is a form of precipitation that occurs when temperatures drop below freezing. It consists of ice crystals that cluster together to form snowflakes, which fall to the ground when they become heavy enough. Snow can accumulate on the ground, creating a white blanket that can affect travel and outdoor activities. Snow plays a crucial role in the environment, as it helps to insulate the ground and provides moisture for plants when it melts. It also contributes to the water supply in many regions, replenishing rivers and lakes during the spring. In addition, winter snow is often associated with recreational activities like skiing and snowboarding, attracting enthusiasts to mountains and resorts.
