Rain, wind, and climate all affect the weathering and leaching of soils.
It is called Leaching
Bauxite is a sedimentary rock that is the main ore of aluminum. Bauxite varies in composition, as does any rock, but the main components are minerals of aluminum oxide and aluminum hydroxide. Bauxite may also contain amounts of iron, clay, silt and silica. Bauxite is the result of the leaching of minerals from tropical soils leaving a hardened clay-like material that is high in the above minerals, which resist leaching. In addition to being the primary source of aluminum, some bauxite is also used in the manufacture of abrasives.
Did you use flat finish instead of semi-gloss? Flat doesn't have as hard of a finish so it lets more of the moisture penetrate. Depending on what was on the wall before, moisture may be penetrating to the plaster or drywall and leaching out minerals that are leaving the stain.
Significant portions of the lithosphere are already "sunk in the hydrosphere". Specifically the oceanic crust. Strictly speaking the hydrosphere includes groundwater so any section of the earth's continental crust where groundwater is present and that is located below the water table could also be described as being "sunk in the hydrosphere". This water, present in pore spaces can have a number of effects, including reducing the effective stress within the rock (which acts to decrease it's strength), cause the leaching or dissolution of various minerals and or the precipitation of minerals.
Illuvation or leaching
The bully was leaching his answer from the smarter children.
role of leaching in nitrogen cycle
what is the difference between elevation and leaching
The boy was leaching onto his mother. Another good sentence would be, the music was leaching on the boy like mud.
Compacted clay soil is fairly impermeable to leaching.
Clay leaching do not affect pH
Leaching
leaching affects soil by pulling all the nutirents from the water by affecting the water

Leaching affects soil by it removes some minerals on horizon A and moves it down to horizon B.
