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 of four where trees can spawn, which can be replanted using the acorns that are dropped by chopping most trees down. Natural caves may be found in this environment, although most are not more than 100 feet deep.

Monsters:


 * Zombie (Night)
 * Doctor Bones (Night)
 * Demon Eye (Night)
 * Slime (Day)
 * Pinky (Day)
 * King Slime (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. Useful if you want a great amount of glass, which is used for different things.

Ocean
Oceans are large expanses of deep water, at both edges of the map. Oceans have sandy beaches, which makes an ocean a nice place to collect large amounts of sand. Oceans may contain underwater chests. Chests that are in the ocean may contain special items such as a Breathing Reed, Flippers, and other water related items. There is a finte amount of water in the oceans.

Underground
Main article: The Underground

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

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.there is also buldings made of copper,gold,iron or silver brick.

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.shadow orbs can be found here in deep thin caves called chams witch can reach all the way to stone layer and rumors of it reaching the underworld {need proof }

Meteorite
Main article: Meteorite

Meteroites can spawn randomly when you break shadow orbs and will land on the map somewhere. used for some late game armor.

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; 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. It is found near or under the crup. You can find more minerals like gold, silver, iron and copper WAY more often then anywere else this also refers to the surface jungle. The base of jungleshrines consists of mud.

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 a lot of lava. Chests can be found here.buldings made of hellstone brick can be found here and is less exspensive then making it {hellstone + ironpick} Hellstone can be used to make molten tools and armor by makeing it by useing lots of hellstone bars (6 hellstone and 2 obsiden), but its hard to get alot of it at once becuse of the fire imps and bone serpents attacking you every second.

Surface Jungle
Main article: Surface Jungle

The Surface 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, Jungle Slimes and Piranha are some of the hostile NPC's that spawn there.
