Time-averaged image, or “timex,” created by averaging the intensity of light recorded at each spot, or “pixel,” during a 17-minute video taken at Madeira Beach, Florida, on June 20, 2017. Blurred white bands show where waves are breaking. Offshore band shows location of a sand bar.

“Variance” image produced from video shot at Madeira Beach, Florida, on June 20, 2017. The more the light intensity changes at a given spot, or “pixel,” during the video, the brighter the value assigned to that pixel. Motion tends to produce changes in light intensity. Note bright bands parallel to shore where waves were breaking.

Ši diagrama parodo tik natūralų vandens ciklą.

Terminas vandens apytaka apibūdina vandens būvį (skystis, garai, ledas) ir jo judėjimą žemės paviršiuje, žemėje ir virš jos. Šis reiškinys vyksta be pertraukos daug daug metų. Nuo jo priklauso žmogaus ir visos gyvosios gamtos egzistavimas Žemėje.
