Avalanche Awareness and Dynamics

The video explores the nature of snowflakes, their accumulation, and the energy they possess. It explains potential and kinetic energy in snow, particularly in the context of avalanches. The video details how snow layers and slopes contribute to avalanche formation and emphasizes the importance of heeding avalanche warnings for safety.

What is the approximate weight of a block of snow that is one foot on each side?

• 40 pounds

• 30 pounds

• 20 pounds

• 10 pounds

What type of energy does snow have due to its position on a mountain slope?

• Kinetic energy

• Thermal energy

• Potential energy

• Chemical energy

What happens when the potential energy of snow is converted into kinetic energy?

• The snow melts

• The snow forms ice

• The snow evaporates

• The snow causes an avalanche

How fast can an avalanche move?

• 100 feet per second

• 200 feet per second

• 300 feet per second

• 400 feet per second

What is one factor that contributes to the formation of an avalanche?

• The temperature of the air

• The layering of snow

• The color of the snow

• The time of day

What type of snow layer is more likely to contribute to an avalanche?

• A light and dry layer

• A heavy and wet layer

• A frozen layer

• A melted layer

What slope condition is necessary for snow to potentially cause an avalanche?

• Covered in ice

• Too steep

• Too flat

• Just right

What can trigger an avalanche when the snow layers and slope are just right?

• A large earthquake

• A small disturbance

• A change in temperature

• A heavy snowfall

Why are avalanches considered dangerous?

• They are rare

• They are unpredictable

• They are loud

• They are fast and powerful

What should you do if you see an avalanche warning while in the mountains?

• Seek shelter and stay safe

• Climb to a higher altitude

• Ignore the warning

• Continue skiing
