Longshore drift is a geological process that causes sediment transport along the Earth's crust by the prevailing oblique winds. With this we can say that the longshore drift happens along the coast line. These winds generate an air stream parallel to the crust line moving the sediments. This process is also known as coastal drift.
The water turns into condesation (clouds) and then it precipitates and turns to rain, which either leads back to transpiration, or it can also lead to percolation.
