Block



Blocks are the basic units of structure in Minecraft. Together, they build up the in-game environment and can be mined and utilized in various fashions.

Textures
The textures on the faces of blocks are 16×16 pixels by default, but players can utilize resource packs that increase the resolution allowing textures to be 32×32, 64×64, 128×128, 256×256, 512×512, or (rarely) 768×768, 1024×1024 and 2048×2048 pixels. No matter what the resource pack, however, most blocks are proportionately one cubic meter. Most blocks have static textures, with the exception of water, lava, portal, fire, sea lantern and prismarine blocks, which have a shifting pattern for each face. All blocks, with the exception of sand, red sand, gravel, anvils and dragon eggs, ignore gravity.

Naturally generated
"Naturally generated" includes blocks that are created through the world seed.

Naturally created
These are blocks that were created by natural events, such as water and lava creating obsidian.

Structures
Same as "naturally generated", but these blocks are created with the "generate structures" option enabled.

Structures
These blocks are generated as part of nether fortresses.
