Water cycle FAQ Frequently Asked Questions
The question library on water related issues
Water can be found everywhere on earth, as most of the earth consists of water; namely the oceans. On land water cannot only be found in taps and toilets, but also outside the house in streams, lakes, wetlands and reservoirs. This is called surface water.

The ground is made up of different types of layers vertically, called the aquifers. Groundwater spreads through the ground horizontally; it moves from the area of infiltration through an aquifer and out to a discharge area, as a part of the water cycle. This can be a well, a lake, a stream or even an ocean. Groundwater normally moves from points of high elevation and pressure to points of lower elevation and pressure. This movement is quite slow, typically only 1 meter or so per year and rarely more than 0.3 meter per day.
