Here's a breakdown:

* Gas: A state of matter where particles are far apart and move freely.

* Solid: A state of matter where particles are tightly packed and vibrate in fixed positions.

Deposition is the direct transition from the gaseous state to the solid state, skipping the liquid state. It's the opposite of sublimation, which is the transition from solid to gas.

Examples of Deposition:

* Frost formation: Water vapor in the air directly changes into ice crystals on surfaces below freezing.

* Snow formation: Water vapor in clouds directly changes into ice crystals, forming snowflakes.

* Dry ice: Carbon dioxide gas is cooled to a solid state, skipping the liquid phase.
