'''Erosions''', also known as '''basins''', are rare [[Minecraft:terrain feature]]s that strip away the [[Minecraft:Terrain features#Surface layers|top layer]] of a [[Minecraft:biome]]'s surface, leaving a one-block deep hole with a stony floor. They can generate in all three [[Minecraft:dimension]]s, and are intentional.<ref>{{bug|MC-1242||randomly missing topmost layers of the landscape|WAI}}</ref><ref>{{bug|MC-212606||Weird Grass Generation|WAI}}</ref><ref>{{bug|MC-229112||strange bug regarding spots where dirt blocks are missing in a random formation|WAI}}</ref><br />
<br />
== Description ==<br />
Erosions occur at the top-most layer of the terrain surface. The first layer is stripped away, and the secondary layer is too small to generate, causing the terrain below to generate at the surface. Erosions are completely random and extremely rare; they can consist of only one block, a few random blocks, or a massive area with rough borders.[[File:Oak on erosion.png|thumb|right|A large [[plains]] erosion]]<br />
=== Overworld ===<br />
In the [[Minecraft:Overworld]], the floors of erosions almost always consist of [[Minecraft:stone]]. They expose ores such as [[Minecraft:coal ore]], [[Minecraft:copper ore]] and [[Minecraft:iron ore]]. In [[Minecraft:badlands]] erosions, [[Minecraft:gold ore]] can also be seen. In badlands and variants, the floor is replaced by [[Minecraft:orange terracotta]]. Erosions in [[Minecraft:Frozen Oceans|frozen oceans]] occur at the freeze layer and replace it with air, followed by [[Minecraft:ice]] or [[Minecraft:water]] below.<br />
<br />
=== The Nether ===<br />
Erosions in [[Minecraft:The Nether]] replace the floor with [[Minecraft:netherrack]]. Nether erosions can expose ore such as [[Minecraft:nether gold ore]] and [[Minecraft:nether quartz ore]]. Because erosions generate independent of the y-axis, if an erosion generates in an overhang in the Nether, an identical erosion is guaranteed to generate at the exact same x and z coordinates on the ground below such an overhang.<br />
=== The End ===<br />
Since erosions generate before features, [[Minecraft:chorus plant]]s can take root in [[Minecraft:End]] erosions. The floor of End erosions is always [[Minecraft:end stone]].<br />
<br />
== Generation ==<br />
{{see also|Surface rule#Surface depth|Tutorial:Custom world generation#Erosion}}<br />
When the game generates new chunks, the <code>surface depth</code> is calculated for every column inside the chunk based on the <code>minecraft:surface</code> [[Minecraft:noise]]. This integer is used to create variation in the depth of [[Minecraft:stone]] below the surface layers.<br />
<br />
When it is less than or equal to 0, the effect extends to the top block from the surface and replaces it with [[Minecraft:air]]. Note that because surface depth is calculated per-column, every surface in the column is removed; that is, an identical erosion appears above or below another one if there is an overhang. The surface depth rarely reaches these values, eliciting the rarity of erosions. After the hole is generated, the floor is replaced with a stone block of the respective dimension, and the hole is flooded with [[Minecraft:water]] if it is at or below [[Minecraft:sea level]].<ref>{{bug|MC-130788||"Basin" structure is flooded since part of it generates below sea level}}</ref><br />
<br />
Erosion generation occurs before [[Minecraft:carver]] creation in the [[Minecraft:terrain generation]] process, meaning that [[Minecraft:cave]]s, [[Minecraft:features]], and [[Minecraft:structures]] can disrupt or even completely conceal them. As a consequence, [[Minecraft:ore blob]]s are commonly found in erosions, making ore more accessible to players on the surface.<br />
<br />
=== Accidental removal ===<br />
{{IN|je}}, erosions have stopped generating in all biomes except [[Minecraft:Frozen Ocean|frozen oceans]] and [[Minecraft:Deep Frozen Ocean|deep frozen oceans]] since the addition of [[Minecraft:surface rule]]s, which is unintentional behavior.<ref>{{bug|MC-264579||Basins are missing in most biomes}}</ref><br />

== Trivia ==<br />
* The End has few surface features, and no carvers, making End erosions easy to spot.<br />
* This is the only [[Minecraft:terrain feature]] that generates in all three [[Minecraft:dimension]]s.<br />
