What is frost?

Browse → Nature → Weather

Have you ever heard of something called “water vapor”?? Water vapor refers to water when it’s in the form of a gas instead of in the form of a liquid (like drinking water) or a solid (like ice cubes). It might be a little hard to understand, but it plays a big role in our weather!

One thing that happens when water vapor freezes is that snowflakes can form, but another thing that can happen is frost! Frost refers to the white or clear ice crystals that cover surfaces such as plant leaves, windows, sidewalks, and more! 

Unlike snow, which forms in the air and then falls from the sky, frost grows closer to the ground on cold surfaces. Frost is the result of water vapor in the atmosphere that freezes directly into its solid state (ice) without first passing through its liquid state (water). – Neat!!
