Maintaining acidity- <span>In case the pH in the environment drops a lot (becomes very acidic), there is a flux of H ions from the cell's cytoplasm into the cell's vacuole thereby increasing acidity to required level and thus maintaining the </span><span>specific pH </span><span>in the cells internal environment as well.
Turgidity- </span><span>Vacuoles regulate the turgidity by regulating the amount of water inside the cell. </span>
cell has excessive water:<span> vacuole absorbs the water and then diffuses it out of the cell.</span>
cell lacks water<span>: water from the vacuole gets passed back into the cell thereby maintaining turgidity.

It stays in the air to up to 6 to 8 hours
4) rainfall
the factors that affect the soil formations are the amount and seasonal distribution of temperature and rainfall. Climate<span> controls the type and effectiveness of </span>weathering<span> of the parent material, the quantity of water seeping through the soil and the type of micro-organisms present therein.</span>
