Gravel is generated in disks in rivers, oceans and pools. It is a source of flint. Running out of resources can be an issue on Superflat worlds where resources are less plentiful. Technically, gravel and clay are renewable through some unorthodox methods – clay by Mason villagers after a raid, and gravel through piglin bartering.
By tilling coarse dirt, gravel can be converted into dirt. Since gravel is renewable through bartering with piglins, this makes dirt renewable.
Crafting and Use in Minecraft
The crusher turns stone to cobblestone, cobblestone to gravel and gravel to sand. It would be better to add a Hammer for this use. Gravel should have more uses before becoming renewable.
Dirt is now renewable due to the wandering trader selling podzol.
Retrieval and Environmental Details
Ocean floors have lots of gravel. The rarest biome is Modified Jungle Edge. This needs specific conditions to spawn.
Sand, gravel and stone are aggregates. They were previously considered non-renewable resources, but now gravel is renewable by bartering with piglins.
To get gravel, break it with any tool. It has a 10% chance of dropping flint. Other uses include making concrete powder. Falling dust particles have been added for unsupported gravel.
Items can suffocate in slime blocks. If you don’t pick up items within 5 minutes of death they disappear. To remove gravel, break it with any tool.
