An avalanche is a rapid flow of solid snow and ice, consisting of thick layers rather than loose particles. When the surface layers of snow are unsupported by those beneath, they break apart and slide down, causing destruction in their path.

What is an avalanche primarily composed of?

• Loose particles of snow

• Solid snow and ice

• Water and mud

• Sand and gravel

How are avalanches different from loose snow slides?

• They are made of water

• They consist of thick layers

• They occur in summer

• They are slower

What happens when the surface layers of snow are not supported?

• They melt slowly

• They form ice

• They break apart and slide down

• They become stronger

What is the result of an avalanche sliding down?

• It creates new snow

• It causes destruction

• It forms a river

• It stops midway

Which of the following is NOT a characteristic of an avalanche?

• Destructive path

• Loose particles

• Rapid flow

• Thick layers
