Which process is gas turning directly into solid?

Explanation:
Think about how matter changes state when energy is removed. If a gas loses enough energy, its particles can lock directly into a solid structure without becoming a liquid first. This direct gas-to-solid change is called deposition, which is why frost forms on surfaces from water vapor in cold air. By contrast, condensation is gas turning into a liquid, sublimation is solid turning into gas, and boiling is a liquid turning into gas.
