A diagram showing the major orbital resonances in the Kuiper belt caused by Neptune: the highlighted regions are the 2:3 resonance , the nonresonant "classical belt" (cubewanos), and the 1:2 resonance . Neptune's orbit has a profound impact on the region directly beyond it, known as the Kuiper belt.
The current Venusian atmosphere has only ~200 mg/kg H 2 O(g) in its atmosphere and the pressure and temperature regime makes water unstable on its surface. Nevertheless, assuming that early Venus's H 2 O had a ratio between deuterium (heavy hydrogen, 2H) and hydrogen (1H) similar to Earth's Vienna Standard Mean Ocean Water of 1.6×10 −4, [7] the current D/H ratio in the Venusian atmosphere ...
The following outline is provided as an overview of and topical guide to Neptune: . Neptune – eighth and farthest known planet from the Sun in the Solar System.In the Solar System, it is the fourth-largest planet by diameter, the third-most-massive planet, and the densest giant planet.
Neptune has long been known to have white clouds circling it, but images of the furthest planet in the solar system have shown this changing over time - the most recent image, taken by the Hubble ...

English: Diagram of the planet Neptune. Upper atmosphere, top clouds. Atmosphere consisting of hydrogen, helium, and methane gas. Mantle consisting of water, ammonia, and methane ices. Core consisting of rock (silicates and nickel-iron).
The water cycle is also essential for the maintenance of most life and ecosystems on the planet. Human actions are greatly affecting the water cycle. Activities such as deforestation, urbanization, and the extraction of groundwater are altering natural landscapes (land use changes) all have an effect on the water cycle.
