The Water Cycle is also known as the hydrologic cycle and it is the journey that water takes to circulate from the land to the sky and back again. Heat from our sun provides the energy needed to evaporate the water from the Earth’s surface which mainly comes from our oceans which cover most of the planet. Plants also lose water to the air which is called transpiration.
97% of all water on earth is salt water so thought I would discuss desalination. Desalination means, to remove the salt from the saltwater and the main most common process is distillation. Although it is still not cost effective yet, many cities are forming desalination plant programs in order to meet the demands for clean water.
Why can’t we drink salt water when dehydrated?
The simple answer is that the body cannot get rid of all the salt in the salt water without getting rid of more water than was actually consumed. Because kidneys can only produce water slightly less salty than salt water this is the case. When dehydrated, drinking salt water is worse than holding out for fresh water.
There are many methods that can be used to recreate what the earth does naturally but the most basic is the method of boiling water. Boiling causes the water to evaporate leaving the salt behind. Next the evaporated water needs to condensate and collect into a separate container where it can precipitate and become a vessel of purified water.
By only boiling water you can disinfect and kill many contaminants but by distilling you help make sure that other particles such as minerals and other impurities are left behind. The result is nearly pure water!
What is the effect of climate change on the water cycle?
Many believe that global warming only causes drought but it can also cause heavy rains. Main reason for changing the common term to global climate change is the far reaching impacts. Rising warmth causes more evaporation and in turn larger storms. More evaporation also leaves the soil dry and hard which cause rain water to run quickly into rivers and streams leaving the soil once again more dry and in drought.
Man-made responses to climate changes effect to the water cycle?
There is a lot of evidence to prove how man is to blame for our current environmental status. There are currently many measures in place to help reduce the carbon footprint that our society leaves. There are also many theories about how the government combats global climate change and how this also may effect the water cycle in a negative way including but not limited to the health of the population.
One of the many theories have to do with chem-trails. This subject alone is an entire article in itself but I will only lightly touch the subject in reference to the water cycle here. It has been speculated all over the internet that the governments intent is to blast particles into our atmosphere in order to reflect 1% of the sunlight and slow the affects of global warming which would also hinder evaporation. Research has shown that particles such as aluminum oxide doesn’t cause widespread harm to humans but I could also argue that research studies in the 50’s also didn’t show harm was caused by smoking cigarettes. Again, without going into further detail losing the focus of this article I would like to touch lightly again on the man made implications.
