Environments

The world of Terraria consists of ten officially mentioned environment types, also known as biomes.

If you had a hard time finding theses biomes such as the Floating Islands, you can use these tools to locate them.

Forests


Forests are the only biome that can spawn small and large trees, which can be replanted using the acorns that are dropped by chopping them down. Natural caves may be found in this environment, although most are not more than 100 feet deep.

Monsters:


 * Zombie (Night)
 * Demon Eye (Night)
 * Slime (Day)
 * Pinky (Day)

Deserts
Large sandy areas that are occasionally generated. Nothing, however, is particularly special about them, as they are completely barren. They have the same monsters as forests.

Ocean
The ocean has the least features of any environment in the game. Both edges of every map have a sandy beach followed by an enormous (but limited) body of water. The water goes deeper as the player goes further out. Exploration without a means to swim will likely result in drowning, and there isn't much to see anyway. The bottom of the ocean floor frequently has one or more chests containing a Breathing Reed or Flippers.

Underground
Main article: The Underground

The underground consists of three layers: the dirt layer, the rocky dirt layer and the stone layer.

Floating Islands
Main article: Floating Islands

Floating Islands are masses of land that appear in the sky. Just like in forests, you can find trees and grass growing over dirt blocks, with some stones and ores in the ground.

The Corruption
Main article: The Corruption

The Corruption forms during the creation of a map at a random position. In most cases there are at least 1-3 Corruptions per map. The Corruption spawns higher-level monsters regardless of time and should be avoided initially.

Meteorite
Main article: Meteorite

After smashing a Shadow Orb, a Meteorite will crash into the planet. This may also occasionally occur without a shadow orb being destroyed. It is a small area, but should be avoided by lower-level players. The Meteorite itself is made of Meteorite Ore, a high-level material that harms the player on contact unless they have an Obsidian Skull equipped.If you dont have an obsidian skull, you can also use dynamite if you are lazy.

Underground Jungle
Main article: Underground Jungle

The Underground Jungle is a very remote area of the world, residing deep underground. Like Dungeons, these areas have few dead ends;dwfsgadghagagag unlike Dungeons, however, they are covered in plants. They have special items that are found in Jungle Shrines, small buildings made of gold blocks that are spawned at random locations in the Underground Jungle.

Dungeons
Main article: Dungeon

Dungeons are enormous buildings found close to the edge of a generated world, spanning many layers deep. They're filled with treasure chests and unique items.

The Underworld
Main article: The Underworld

The Underworld (Hell dungeon) is a hellish realm (about 3500 Feet below) reachable by digging past the stone layer and is very easily identified by its background of stone with veins of lava. The main structure is hellstone ore deposits surrounded by ash blocks, which is then surrounded by alot of lava. Chests can be found here.

Overground Jungle
Main article: Overground Jungle

The Overground Jungle is a jungle on the surface, containing different trees and NPC's. The trees auto-grow, so planting acorns is not needed. The trees are slightly different than the normal ones, as they're wider at the top. Jungle Bats and Jungle Slimes are some of the hostile NPC's that spawn there.
