In Minecraft, a “flat world” is a world type that generates a flat landscape, as opposed to the default world type, which generates a more varied terrain. Flat worlds are often used for building projects or other large-scale creations, as they provide a large, flat area to work with.
Flat worlds can be created in Minecraft using the world creation settings. When creating a new world, simply select the “Flat” world type from the list of options. You can then customize the world’s settings, such as the size of the world, the height of the terrain, and the presence of structures and resources.
