Falling Block

A falling block is an entity form of block that appears when a gravity-affected block loses its support.

Spawning
Falling blocks spawn where gravity-affected blocks lose their base of support. These blocks include:

Behavior
A falling block continues falling until it lands on another block. After landing, if the block in its place (the coordinates of the center at the bottom of its collision box) is replaceable (such as grass, water, vine, air, etc.) then the falling block returns to its block state. Otherwise, it breaks and drops as an item.

Like most other entities, falling blocks are affected by explosions and bubble columns, can be launched by a moving slime block (although they do not bounce on stationary slime blocks), can be pushed by pistons, and can slide down the side of a honey block. However, they do not have health, cannot be attacked and do not take damage. They are also immune to all status effects. They can be removed with the command.
