Snow

Snow is a form of precipitation that consists of ice crystals. It forms when water vapor in the atmosphere condenses directly into ice without first becoming liquid water. This process is known as deposition.

Formation of Snow

Snowflakes are formed when water vapor in the atmosphere condenses and freezes around a tiny dust or pollen particle in the clouds. As the crystals grow, they take on various intricate shapes due to the temperature and humidity conditions they encounter during their descent to the ground.

Physical Properties of Snow

Snow is composed of individual ice crystals that join together to form snowflakes. The structure of snow can vary greatly depending on factors such as temperature, humidity, and wind. Freshly fallen snow is typically light and fluffy, while older snow can become denser and more compacted over time.
