Small floating bits of dirt

Minecraft generates beautiful landscapes but every once in while you get tiny floating blocks that defy gravity. These hills and caves mark the border between the snow biome and regular nature. Near the center top close to the clouds you can see a couple of blocks of dirt that aren’t attached to anything. It’s only about 7 blocks, but small bits like this have a tendency to ruin the views and landscapes, albeit in a miniscule way.
