Air represents unoccupied spaces. Although it is internally treated as every other block, air cannot be kept in the inventory and can only be destroyed or created by the placement or removal of other blocks, respectively. Air and non-solid blocks are the only spaces the player and other mobs are allowed to move within without mods or glitches. The sole exception is the Ender Dragon which can move within Obsidian, Bedrock, and End Stone.
Clouds
There are two types of clouds: 2-dimensional and 3-dimensional. Pre-indev releases had 2-dimensional clouds, while post-indev releases have 3-dimensional clouds. The player also has the option to turn the clouds from 3-dimensional to 2-dimensional and vice versa via the "fast/fancy" option in the graphics section in the options menu. Clouds can be disabled in the video options. Clouds have no hit-box, they are just visual. Clouds in Minecraft Pocket Edition are similar to Indev and Infdev.

| ? | Air affected liquid blocks that were horizontally adjacent to it. If air was touching the fluid block, there was a 2/3 chance the fluid block would disappear and make the pool recede and a 1/3 chance the fluid block would fill the air, making the pool spread. | ||||

Trivia
- It is possible to survive without air, because other non-solid blocks (that aren't fluid blocks) won't drown or suffocate the player.
- Small boxes of air can spawn commonly in ocean biomes and lakes.
