Snow

Snow is a form of precipitation that occurs when water vapor in the atmosphere freezes into ice crystals and falls to the ground. It is a common occurrence in colder climates and plays an important role in the Earth's water cycle.

Formation of Snow

Snow forms when the temperature in the atmosphere is below freezing (0°C or 32°F) and there is enough moisture present in the air. Water vapor condenses and freezes around tiny particles in the atmosphere, forming ice crystals. These ice crystals then join together to form snowflakes, which can range in shape and size depending on the temperature and humidity at different altitudes in the atmosphere.

Types of Snowflakes

Snowflakes can be categorized into different types based on their structure and shape. Common types of snowflakes include dendrites, needles, columns, and plates. Each type has its own unique characteristics and forms under specific weather conditions.
