What Percentage of Snow Is Water? Understanding Snow Composition

Discover how much water is actually in snow and why melting snow yields less water than its volume suggests.

Video transcript

Snow typically contains about 90% air and 10% water. The actual percentage can vary based on factors like temperature and snow density, but the water content generally remains quite low. This is why melting snow results in much less water than its original volume as snow.

Questions and answers

  1. Why does melted snow produce less water than the volume of the snow?

    Because snow contains about 90% air, its volume is much larger than the actual water content. When snow melts, the air is lost, resulting in much less water than the original snow volume.

  2. How does temperature affect the water content in snow?

    Temperature and snow density influence how much water is in snow; colder temperatures often result in fluffier snow with more air and less water content.

  3. What determines the density of snow?

    Snow density is affected by factors such as temperature, humidity, and how the snowflakes compact over time.
