Frost is mainly formed from what?

Answer and explanation

Correct answer: From water vapour forming ice crystals

Direct answer: B. Frost mainly forms when water vapour near a cold surface changes into ice crystals, usually under freezing conditions. The crystals deposit on leaves, grass, soil or other exposed surfaces and create a white frozen coating. A is wrong because liquid rainfall is falling water; it is not the normal source or definition of frost. C is wrong because sea waves do not produce frost on land. D is wrong because boiling groundwater is unrelated to the formation of ice crystals in the atmosphere. The important chain is: moisture in air, a sufficiently cold surface, and freezing or direct ice deposition. Do not confuse frost with dew: dew is liquid, while frost is solid ice.
