Solid block



Solid block is the term for a block which the player cannot walk through. Most block types are solid, while most plant types are not. Cacti, wood, pumpkins and leaves are all examples of solid plant blocks. Ladders may not seem solid, but it is possible to stand atop them without descending.

Both water and lava are not solid, and can be passed through (although passing through lava will deal damage to the player, so this is strongly not recommended.). Every type of solid block, with the exceptions of bedrock can be destroyed and collected.

The only exception is Soul Sand (found in the Nether) in that when you step on to it your speed is slowed and you'll sink slightly into it, making it a half solid block. Soul Sand has other characteristics different to normal blocks such as when it's placed on top of ice or in water its slowing effects are strengthened. It is also 7/8 the height of a normal solid block. These characteristics make it an abnormal solid block.
