Gravel is a medium grey block with dark grey marks on it. Its previous texture had a pink/purple tint, but this was changed.
Gravel's abundance and gravity-obeying property makes it useful for a variety of tasks, along with its gravity-obeying partner, Sand . For exploration, it can be used to quickly build pillars to reach heights that are easy to dismantle after. They can also be used to quickly fill in Water or Lava lakes by dropping them on the edges or against overhead blocks, so that they fall and occupy the fluids. Filling caves in with Gravel is a quick way to prevent mobs from spawning. Mobs can be suffocated with Gravel, too. This is an efficient way to raid a dungeon. If mined, Gravel has a slight chance of dropping Flints . If using a Tool with the Fortune Enchantment, however, there is a 100% chance the player will find Flints.
Gravel is also commonly used for traps where pistons move down, allowing the gravel to move down as well, so something else such as water or lava will flow in where the gravel was, effectively making a bridge across a moat. This saves the player from having to use Slimeballs for Sticky Pistons . Another trap that Gravel is useful for is setting a suffocation trap. This is where pistons would be triggered and retract sideways, allowing the gravel to fall on top of whoever was below.
