The process by which water vapor changes directly to a solid is called deposition.

Here's a breakdown:

* Water vapor: This is the gaseous state of water, invisible to the naked eye.

* Solid: In this case, the solid is ice.

* Deposition: This is the process where water vapor skips the liquid phase and transitions directly to solid ice.

Examples of deposition in nature:

* Frost: When the air temperature drops below freezing, water vapor in the air can deposit directly onto surfaces, forming frost.

* Snow: Snowflakes form in the atmosphere when water vapor deposits onto tiny dust particles, building up into intricate ice crystals.
