sublimation: Sublimation is when ice evaporates directly into vapor without first melting into the water phase.
threatened: When species are not quite endangered but their numbers are low, they are considered threatened.
Sublimation: The transition of water directly from the solid state to the gaseous state, without passing through the liquid state; or vice versa. Compare condensation, evaporation.
Sublimation: The transition of a substance from the solid phase directly to the vapor phase, or vice versa, without passing through an intermediate liquid phase.
sublimation A process by which solids will volatilize.
sublittoral Below the lake or seashore; the area between the low-tide mark and 20 fathoms.
ablation (glacial) All processes, which include melting, evaporation (sublimation), wind erosion, and calving (breaking off of ice masses), that remove snow or ice from a glacier or snowfield.
Fumes: Airborne particles, usually less than 1 micrometer in size, formed by condensation of vapors, sublimation, distillation, calcination or chemical reaction.
Fumigant: A biocide that is vaporized to kill pests. Used indoors or outdoors.
