What determines the shape of a snowflake?

• Temperature and humidity

• Wind speed

• Altitude

• Time of day

Why do snowflakes have six sides?

• Because of the hexagonal shape of water molecules

• Due to the wind patterns

• Because they are made of six ice crystals

• Due to the Earth's rotation

What happens to water vapor when the air is cold enough?

• Water vapor freezes into ice immediately.
• Water vapor turns into tiny ice crystals

• Water vapor remains unchanged in cold air.
• Water vapor evaporates into the atmosphere.

What role does humidity play in the formation of snowflakes?

• High humidity can lead to more complex snowflakes

• Humidity has no effect on snowflakes as they form only from cold air.
• Humidity is only important for rain, not for snowflakes.
• Humidity is crucial for the formation of snowflakes as it supplies the water vapor that freezes into ice crystals.

What is the significance of the shape of snowflakes?

• The shape of snowflakes is purely random and has no significance.
• Snowflakes are shaped by the temperature of the ground they land on.
• The shape of snowflakes determines their color and brightness.
• The shape of snowflakes indicates the atmospheric conditions during their formation and reflects the unique molecular structure of ice.

What influences the final shape of a snowflake as it falls to the ground?

• The path it takes and the temperature and humidity during its descent.

• The altitude at which it forms.
• The speed of the wind during its fall.
• The color of the snowflake's surface.

How does temperature affect the size and complexity of snowflakes?

• Warmer temperatures lead to larger and simpler shapes, while lower temperatures result in smaller and intricate shapes

• Snowflakes are always the same size regardless of temperature.
• Temperature has no effect on snowflake size or complexity.
• Higher temperatures create larger and more complex snowflakes.

Why is the amount of moisture in the air crucial in snowflake formation?

• Moisture only affects the temperature of the air.
• Moisture affects the complexity and shape of the snowflake.

• Moisture is irrelevant to snowflake formation.
• Moisture prevents snowflakes from forming.

Summarize the conclusion about snowflakes mentioned in the text.

• Each snowflake is unique.
• All snowflakes are identical.
• Snowflakes are made of ice crystals only.
• Snowflakes fall in a straight line.
