On average, thee planet receives approximately 100 centimeters of precipitation annually, but distribution is extremely uneven. Deserts receivesves than 25 cm per year, while some tropical mounderiver 1,000 cm.

Infiltration andd Percolation

Once precipitation reaches thee ground, part of it sinks into the soil the distribugh infiltration. The rate depends on soil type, vegetation cover, and satislation levels.
