Dirt

Dirt naturally generates on much of the surface of the world of TerraFirmaCraft. It changes color based on the rock type of the land around it. Unlike Vanilla, dirt is affected by gravity, meaning it will fall if unsupported, a behavior shared by sand, gravel, and cobblestone. It also cannot usually be stacked more than one high, meaning that walls made of dirt will collapse. This behavior often causes near-surface caves to collapse.

Grass can spread onto dirt, as it does with clay and peat. Grass is still affected by gravity. Dirt can be tilled with a Hoe to turn it into farmland, which will grow crops.
