Gravel is a block characterized by its gray, speckled appearance and its tendency to fall due to gravity, unlike most other blocks. It can be found in abundance near water bodies and underground. When mined, it has a chance of dropping flint, which can be used to create arrows or flint and steel. Its falling property also allows players to use it for traps or to clear out other blocks by dropping gravel on them.
