Yes, water below your feet is moving all the time, but, no, if you have heard there are rivers flowing below ground, that is not true. Water moves underground downward and sideways, in great quantities, due to gravity and pressure. Eventually it emerges back to the land surface, into rivers, and into the oceans to keep the water cycle going.

Evapotranspiration can be defined as the sum of all forms of evaporation plus transpiration, but here at the Water Science School, we'll be defining it as the sum of evaporation from the land surface plus transpiration from plants.

Note: This section of the Water Science School discusses the Earth's "natural" water cycle without human interference.

Millions of cubic miles of water exists in the ground. You can't see it, but not only is it there, it is always moving around -- mostly downward, but also horizontally. Moving groundwater helps keep rivers full of water and allows for people to draw out water via wells. Moving groundwater is an important part of the water cycle.

The oceans are, by far, the largest reservoir of water on earth — over 96% of all of Earth's water exists in the oceans. Not only do the oceans provide evaporated water to the water cycle, they also allow water to move all around the globe as ocean currents. Oceans are the storehouses of water nature uses to run the water cycle.

Veeringe, The Natural Water Cycle, Estonian

Mis on veeringe?

Mis on veeringe? Sellele on lihtne vastata - see olen mina, vesi, igal pool! Veeringe kirjeldab vee olemasolu ja liikumist Maa peal, sees ja kohal. Maakeral on vesi alati liikvel ning oma olekut muutmas - vedelast auruks ja jääks ning uuesti vedelaks. Veeringe on toiminud miljardeid aastaid ning sellest oleneb kogu elu...
