Final answer:
The water equivalent of snowfall for dry, powdery snow is lower compared to wet snow.
Step-by-step explanation:
Snow is formed from ice crystals and is the solid phase of water. Dry, powdery snow is made up of tiny ice particles that are not densely packed. When the snowfall is dry and powdery, there is less water content in the snowflakes. Therefore, the water equivalent of snowfall for dry, powdery snow is lower compared to wet snow.
For example, if you have 10 centimeters of wet snow and 10 centimeters of dry, powdery snow, the amount of water in the wet snow will be greater than in the dry, powdery snow.
In summary, the water equivalent of snowfall for dry, powdery snow is lower compared to wet snow due to the lower water content in each snowflake.
