Grass Block



Grass is a common block that is on the ground on newly generated maps. It looks like a dirt tile with grass on the top. It requires sunlight to continue to exist and will revert to dirt slowly if sunlight is removed. Dirt will also change to grass over time if there is another grass block next to it and it's receiving sunlight. Also if the grass is flooded by water, it will slowly disappear. If there are no grass blocks on the map then grass will cease to spawn entirely. Grass is unable to be created directly by players.

Grass and dirt changing between each other is a common cause of chunk updates.
