The picture illustrates the way in which water passes from ocean to air to land during the natural process known as the water cycle. Ocean water evaporates, falls as rain, and eventually runs back into the oceans again.
Beginning at the evaporation stage, we can see that 80% of water vapour in the air comes from the oceans.
It cools and rises, becoming clouds, which eventually condense into water droplets.
Depending on the temperature of the atmosphere and other conditions, the water precipitates as rain, sleet, hail or snow.
Otherwise, rainwater may filter through the ground, reaching the impervious layer of the earth.
Salt water intrusion is shown to take place just before groundwater passes into the oceans to complete the cycle.There are different parts of the hydrologic cycle that have an impact the climate.Some of these parts contribute certain effects of climate change like droughts, melting glaciers, decreasing river flows, and much more (textbook).Because the climate of the Great Plains is arid, water in the aquifer is being used faster than it can be recharged.That's why some scientists refer to using fossil water aquifers as water mining. Images from the Mars Global Surveyor spacecraft show what looked like gullies carved out by rivers of water on the surface of the planet.The sun drives the entire water cycle and is responsible for its two major components: condensation and evaporation.When the sun heats the surface of water, it evaporates and ends up in the atmosphere as water vapor.At the third stage in the cycle, rainwater may take various paths.Some of it may fall into lakes or return to the oceans via ‘surface runoff’.As our need for water outweighs the Earth's supply, scientists wonder if we may one day mine for water on the other planets and moons in our solar system.Water has a lot of unique and amazing properties that make it so important to life.
