How Do Snowflakes Form?

The video explores the intricate beauty of snowflakes, explaining their formation from water vapor in clouds at temperatures of 0°C or lower. It discusses how factors like temperature, humidity, and altitude influence their shapes, ranging from simple hexagonal plates to complex stellar dendrites. The symmetry of snowflakes is due to the ordered arrangement of water molecules forming a lattice. However, snowflakes can also pose dangers, as their accumulation can lead to avalanches, highlighting the dual nature of these fascinating structures.

What factors influence the formation of different types of snowflakes?

• Sunlight and air pressure

• Soil type and vegetation

• Temperature, humidity, and altitude

• Wind speed and direction

How do snowflakes typically form in terms of shape?

• Circular

• Rectangular

• Hexagonal

• Triangular

What happens to snowflakes as the temperature drops further below freezing?

• They turn into rain

• They become more complex

• They disappear

• They melt

What causes the symmetry in snowflakes?

• The presence of sunlight

• The arrangement of water molecules in ice

• The speed of falling snow

• The color of the sky

What potential danger can snowflakes cause when they form unstable layers?

• Flooding

• Avalanches

• Tornadoes

• Earthquakes
