thumb|upright=1.35|A patch of grass showing three zones.
I cannot write an accurate overview of "frost" based solely on the provided context, as it contains only an image caption describing "a patch of grass showing three zones" without any information about frost itself. To provide an accurate, factual overview based only on your context, I would need source material that actually explains what frost is and why it matters.

Frost is a layer of ice on a solid surface, which forms from water vapor that deposits onto a freezing surface. Frost forms when the air contains more water vapor than it can normally hold at a specific temperature. The process is similar to the formation of dew, except it occurs below the freezing point of water typically without crossing through a liquid state.
