Dirt

Dirt is a block in Minecraft Pocket Edition that was added in Pre-Release. It is a commonly available block as it spawns in every biome (except Desert and Mesa Biomes). It can be mined by using a Shovel or hand. It was the first block added into the game. It can also be found underground.

Grass
Main Article: Grass Block

When Dirt is placed in a light level of 9 or above, it can turn into a grass block if there is a grass block directly adjacent to it.

Uses
Dirt is mostly used for Farming by converting it into Farmland using a hoe. However, it can also be used as an abundant building block, or for climbing to high distances as it is easily broken.
