Water Cycle Components

Earth's water is always in motion, and the natural water cycle, also known as the hydrologic cycle, describes the continuous movement of water on, above, and below the surface of the Earth. Water is always changing states between liquid, vapor, and ice, with these processes happening in the blink of an eye and over millions of years.

Springs and the Water Cycle

A spring is a place where water moving underground finds an opening to the land surface and emerges, sometimes as just a trickle, maybe only after a rain, and sometimes in a continuous flow. Spring water can also emerge from heated rock underground, giving rise to hot springs, which people have found to make a delightful way of soaking away their problems.

Ice, Snow, and Glaciers and the Water Cycle

Ice and glaciers are part of the water cycle, even though the water in them moves very slowly. Ice caps influence the weather, too. The color white reflects sunlight (heat) more than darker colors, and as ice is so white, sunlight is reflected back out to the sky, which helps to create weather patterns. Read on to learn how glaciers and ice caps are part of the water cycle.

Kolobeh Vody, The water cycle for schools, Slovak

Mohli by ste si myslieť, že každá kvapka dažďa, ktorá spadne z oblohy alebo každý pohár vody, ktorý vypijete, je z čisto novej vody. V skutočnosti je to ale stále tá istá voda, ktorá tu je a bola vždy a ktorá je trvalou súčasťou kolobehu vody!
