Question

which process could cause ice to form a thin layer over a lake?
freezing
sublimation
evaporating
condensation

Explanation:

Freezing is the phase change where liquid water turns into solid ice, which is the process that forms a thin ice layer on a lake. Sublimation is solid to gas, evaporating is liquid to gas, and condensation is gas to liquid, none of which create solid ice from lake water directly.

Answer:

freezing
