The water cycle is powered from the energy emitted by the sun. This energy heats water in the ocean and seas. Water evaporates as water vapor into the air.Some ice and snow sublimates directly into water vapor.
The deep water cycle, or geologic water cycle, involves exchange of water with the mantle, with water carried down by subducting oceanic plates and returning through volcanic activity, distinct from the water cycle process that occurs above and on the surface of Earth. [1]

The dam of the Cañon del Pato hydroelectric plant was also destroyed, although the power station itself was unharmed. [1]: 12 At Huallanca below Cañon del Pato, the river reportedly dried up for an hour after the earthquake, due to its temporary blockage upstream, then abruptly rose 20 m (66 ft) from its bed. After the water receded "dozens ...
On 18 April 2014, seracs on the western spur of Mount Everest failed, resulting in an ice avalanche that killed sixteen climbing Sherpas in the Khumbu Icefall.This was the same icefall where the 1970 Mount Everest disaster had taken place.
Afghanistan is prone to a wide range of natural disasters. The United Nations (UN) estimated that 250,000 Afghans are affected by such disasters each year. [1] Between 1980 and 2015, Afghanistan had the second highest number of fatalities caused by natural disasters globally. [2]
