  • What Is Percolation in Relation to the Water Cycle

    Percolation is part of the water cycle that occurs after precipitation and before storage during which water filters down through aerated soil due to gravity. After percolation, water is stored in groundwater reservoirs until it reaches a point where sunlight warms it and the water evaporates.
