Science of Snowflakes Quiz

What is the term used to describe the symmetrical pattern of snowflakes?

• Bilateral symmetry

• Geometric symmetry

• Radial symmetry

• Asymmetry

How are snowflakes different from regular frozen droplets of water?

• Snowflakes are always perfectly symmetrical

• Snowflakes have a different chemical composition

• Snowflakes are larger in size

• Snowflakes form slowly and grow in the cloud

What are the two basic ways that a snowflake can grow?

• Forming facets and forming branches

• Forming facets and forming spikes

• Forming branches and forming layers

• Forming branches and forming spikes

What determines the basic shape of an ice crystal in a snowflake?

• The speed at which it falls

• The size of the particle it forms on

• The location where it forms

• Temperature and humidity of the air

What causes the formation of branches in a snowflake?

• Melting and refreezing of the ice crystal

• Condensation of water vapor on the edges of the crystal

• Condensation of water vapor on bumps or irregularities

• Interaction with other snowflakes in the cloud

What determines the intricate shape of a single arm of a snowflake?

• The atmospheric conditions experienced by the entire ice crystal

• The size of the ice crystal

• The speed at which the snowflake falls

• The location where the snowflake forms

Why are no two snowflakes exactly alike?

• Because they have different sizes

• Because they follow slightly different paths from the sky to the ground

• Because they have different chemical compositions

• Because they encounter different atmospheric conditions along the way

What is the internal order of water molecules in a snowflake called?

• Condensation

• Crystallization

• Sublimation

• Evaporation
