			=== Ice ===
			If the upper-most block on the surface is [[Minecraft:water]], an [[Minecraft:ice]] block replaces the water.

			=== Snow ===
			[[Minecraft:Snow]] attempts to generate on the surface if the block is supported for snow layers, e.g. not on [[Minecraft:ice]] or [[Minecraft:dirt path]]. {{IN\|je}}, one snow layer is simply placed on the surface. {{BE}} uses a [[Minecraft:biome]]-dependent snow accumulation algorithm.

			Each biome has two values for snow accumulation. The first value determines the random variation of snow layers. When 0, in most warmer biomes and a few cold, one snow layer is simply added to the surface like in ''Java Edition''. When this value is higher, snow layers are randomized:
			* A noise calculates random patches where no snow generates. Anywhere else, one layer is generated.
			* When a snow layer generates horizontally bordering a full block, one layer is added for each bordering block.
			* A second noise calculates random patches where multiple snow layers generate. The higher the snow accumulation value above 0.125, the larger these patches are and higher snow can accumulate.

			For all snow accumulation values, see {{Slink\|Biome\|List of biome climates}}.<gallery widths="200">

A '''freeze top layer''' is a [[Minecraft:feature]] found throughout the [[Minecraft:Overworld]].

== Generation ==
Freeze top layer is a feature that is used to add snow and ice to mountains and cold [[Minecraft:biome]]s.

Freeze top layer tries to generate in all chunks in the [[Minecraft:Overworld]]. In each chunk, it tries at each block column to generate snow or ice on the terrain surface if the [[Minecraft:Biome#Temperature|biome temperature]] there is cold enough (below 0.15) and the block light level is less than 10. If the surface is water, an [[Minecraft:ice]] block replaces the water. Additionally, [[Minecraft:snow]] tries to generate on the surface if it can attach on the surface's block.

{{el|be}}:
{{IN|bedrock}}, it is technically not a feature. The game simply iterates through each horizontal coordinate after the chunk generation to generate ice and snow.
