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.

This image of the Las Vegas /Lake Mead / Grand Canyon area was acquired on June 16, 2017, with Indian Space Research Organization’s Resourcesat-2 AWiFS sensor. Images of this region can be useful to help detect changes in vegetation and water availability for growing desert communities.

Marker bed known as the Loriolia Bed, found 80 feet below the contact of the Glen Rose Limestone and the Kainer Formation. The photograph was taken north of Farm to Market Road (FM) 195, approximately 1,500 feet west of the intersection of FM 220 and FM 195. The Loriolia texana fossils are identified by white arrows (photograph by Allan K. Clark, U.S.
