Falling blocks are affected by gravity, unlike all other blocks. They were added to the game with version 1.16 There are currently two types of falling blocks: the sand block and the gravel block. These blocks will fall when any block immediately next to them is broken or disturbed some other way. This can be useful for making traps in creative mode. A spike trap, door or trap door activation can trigger the landfall. When the fall is triggered, any and all falling blocks that are touching the falling ones will also fall.
