Answer:

In the same way that we can build a greenhouse using plastics as a cover, the planet has its own roof, not of plastics, but of gases. Our atmosphere presents among its "ingredients" a series of gases known as "Greenhouse Gases" that form a cover that fulfills the same functions as the plastics of our greenhouse: They retain the sun's rays, cause an accumulation of heat and an increase of temperature. What gases are these? Mainly water vapor (H2O), carbon dioxide (CO2), nitrous oxide (N2O), methane (CH4), and ozone (O3) are the main greenhouse gases in the Earth's atmosphere. The Greenhouse Effect is responsible for the current climate change and with it the melting of the poles, the disappearance of glaciers, the increase in the level of the oceans, the disappearance of many life forms, greater number of natural disasters , fires, droughts.

Answer:

Osmosis is a very common phenomenon in nature. Both the body of the Animals and plants such as the human body itself use the Osmosis to perform a large number of processes When two fluids of different density are separated by a membrane semipermeable there is a pressure difference between the two, and the less dense fluid ha to pass the membrane until said pressure is balanced. This is the phenomenon known as osmosis. In Industry, this natural tendency is forced (pressure) to act in the opposite direction in what nature would do. This fact is what gives the name to the system we call Reverse Osmosis. Its applications in civil engineering range from potable water purification, sewage treatment, ultra pure water production to seawater desalination, oil field formation waters treatment.
