Gravel

Gravel is a block that falls under gravity, found in both the Overworld and the Nether. It generates in large patches in rivers, ocean floors, beaches, and stony shores, as well as in the Nether near lava seas. When broken, Gravel drops flint one time in ten, more often with Fortune. It is also obtained through bartering with piglins. Gravel is used to craft coarse dirt and concrete powder. It falls when unsupported and can suffocate players or mobs. When placed under a note block, it produces a 'snare drum' sound.
