Understand that phase changes describe the transition of matter from one state to another: solid, liquid, or gas.
Recall that deposition is the phase change where a substance transitions directly from the gas phase to the solid phase without passing through the liquid phase.
Compare deposition with other phase changes: sublimation is solid to gas, melting is solid to liquid, and vaporization is liquid to gas.
Identify that the correct description of deposition is 'gas to solid' because it is the reverse of sublimation.
Conclude that deposition occurs when gas particles lose enough energy to form a solid directly, bypassing the liquid state.
