Nat Geo Snowflakes Quiz

What is the basic structure of a snowflake?

• Round shape with smooth surface

• Star-shaped with sharp edges

• Rectangular shape with jagged edges

• Hexagonal shape with intricate patterns of ice crystals

How are snowflakes formed?

• Water vapor in the atmosphere freezes into ice crystals

• Snowflakes are formed by the condensation of liquid nitrogen in the atmosphere

• Snowflakes are formed by the collision of two raindrops in the atmosphere

• Snowflakes are formed by mixing salt and sugar in the atmosphere

What factors contribute to the unique shape of snowflakes?

• The color of the sky

• The direction of the wind

• The phase of the moon

• Arrangement of water molecules and varying temperature and humidity conditions

Why do snowflakes have six sides?

• Because they are formed in a hexagonal lattice structure

• Molecular structure of water

• Due to the angle of sunlight hitting them

• Because they are made of ice cream

What is the scientific term for the process of a snowflake melting and refreezing as it falls through different temperatures and humidity levels?

• solid-liquid transition

• ice-melt evolution

• freeze-thaw transformation

• melt-freeze metamorphism

What are some warning signs of a potential avalanche?

• Loud noises from nearby wildlife

• Lack of recent snowfall

• Sunny weather and clear skies

• Cracking or collapsing of snow, recent heavy snowfall or rain, and rapid rise in temperature are some warning signs of a potential avalanche.

What are the different types of avalanches?

• Slab avalanches, powder snow avalanches, and wet snow avalanches

• Ice avalanches, hail avalanches, and sleet avalanches

• Rock avalanches, sand avalanches, and mud avalanches

• Wind avalanches, hurricane avalanches, and tornado avalanches

How can people protect themselves from the danger of avalanches?

• Stay informed, carry safety gear, and take safety courses

• Wear shorts and flip flops

• Go skiing alone without telling anyone

• Ignore weather warnings
