4.3.3. Snow

Try these first

1. 1.

   What is snow?

   Hint

   Think about what makes snow different from rain.

2. 2.

   What temperature must the atmosphere be for snow to form?

   Hint

   Consider the freezing point of water.

3. 3.

   What form does snow take when it falls?

   • Liquid
   • Ice crystals
   • Water droplets

   Hint

   Remember that snow is solid, unlike rain.

4. 4.

   True or False: Snow becomes important when it melts in spring.

   • True
   • False

   Hint

   Think about seasonal changes in water availability.

5. 5.

   Calculate the potential water yield from a snowpack of 1 meter depth over a 100-hectare area, assuming a snow water equivalent of 0.3.

   Hint

   Think about using the area to find total volume and then apply the snow water equivalent.

6. 6.

   Describe the impact of climate change on snowpacks and subsequent water resources.

   Hint

   Consider how temperature changes might affect the timing of melting.
