its the fequair layer
aquifer-is a wet underground layer of water-bearing permeable rock or unconsolidated materials (gravel, Sand, silt, or clay) from which groundwater can be usefully extracted using a water well. WHILE Aquiclude-An impermeable body of rock or stratum of sediment that acts as a barrier to the flow of groundwater
permiable
sediment
allows the exit of hairs through the epidermal surface
The ozone layer protects us from ultraviolet radiations. This layer blocks out all the harmful radiations and allows the good ones to pass through.
An underground layer of spongy rocks that holds water is an aquifer.
It is where a layer of underground water is sandwiched between layers of sediment and rock.
An aquifer is not a type of water. It is an underground layer of permeable rock, sediment or soil that contains water. Wells are dug to reach this layer to obtain water.
A fully permeable layer is a layer that allows all substances to pass through. A partially permeable membrane is a membrane that only allows some substances to infiltrate.
i think its sediment
Peat

The hole in ozone layer is actually the thinning of this layer. This hole allows the harmful UV rays to pass through.
When organisms died in a river or stream of some sort, they are covered in a layer of sediment, as time gos by the sediment hardens and is covered by another layer of sediment and so on.

sediment gathers up then the water in the sediment starts to evaporate. Compaction and Cementation happens then forms layer after layer.
The Plasma Membrane, which has a phospholipid bi-layer.
