frost boil
LowTechnical/Scientific
Definition
Meaning
A mound or swelling of soil caused by freezing and thawing cycles, often found in permafrost regions.
A specific type of patterned ground feature where soil is churned and pushed upward by the growth of ice lenses, forming a boil-like, often circular, hummock.
Linguistics
Semantic Notes
The term is highly domain-specific, primarily used in geomorphology, periglacial geology, and soil science. It describes a natural landform process, not a culinary or medical condition.

- Confusing it with 'frostbite'.
- Assuming it's a common compound noun.
