The Water Cycle(Actual)

  1. 1. The cycle of water Teacher: Jimmy Vergara Gallego. Members: -Ricardo Azaña B. -Luis Montoya Q. Course: Ingles. Degree: 5° of sec.
  2. 3. Introduction <ul><li>Here since podras to see in this work we are going to try to solve many problems of the water that are given in our environment since we themselves disturb it since when one throws alone wrapper and even more if someone sees you for that derrepente this person will do the same thing since we incite the person to do it </li></ul>
  3. 4. Dedication <ul><li>East works I it dedicate to my parents who have taken me for a good way and have given me a good nourishment and in fruit to it I am a person with a good autoesteem and for this motive I try to extract forward to the planet wherefrom we all are and I will treat and it will help in diverse points on the water </li></ul>
  4. 5. Rivers affected in our Country <ul><li>Pitifully there are rivers in danger in our country for an almost ridiculous reason, you make whose directors at least can make like his residues innocuous or that if they know it do not want to do it, and they are filling with pestilence and decomposition the corners mas cozy with our republic. </li></ul>
  5. 6. The character of the pollution of the water <ul><li>The terms(ends) pollution of the water and pollution of the air involve both the presence of strange undesirable matter in a substance, for the rest, &quot;pure&quot; or &quot;natural&quot;. </li></ul><ul><li>Nevertheless, the concept of the pure water is very different from that of pure air. As we saw in the previous topic, the air is a mixture(mixing) of diverse components, and the &quot; pure air &quot; is considered to be, consequently, a particular mixture(mixing) that represents a species(kind) of terrestrial ideal atmosphere. </li></ul>
  6. 7. Effects of the pollution of the water <ul><li>The effects of the pollution of the water include those who concern the human health. The presence of nitrates (you go out of the nitric acid) in the drinkable water can produce a childhood disease that in occasions is mortal. The present cadmium in the fertilizers derived from the ooze or mud can be absorbed by the crops; of being consumed in sufficient quantity, the metal can produce a disorder diarreico sharply(acutely), as well as injuries in the liver and the kidneys. Some time ago that knows itself or is suspected in the dangerousness of inorganic substances, as the mercury, the arsenic and the lead. </li></ul>
  7. 8. Pollution marinades <ul><li>The spillages that come directly to the sea contain toxic substances that the marine organisms(organisations) absorb of immediate form. In addition they form important warehouses in the rivers that suppose in turn an enormous development of new pollutant elements and an excessive growth of undesirable organisms(organisations). These warehouses come from the stations filter systems, of the residues of dredgings (specially in the ports and estuaries), of the graveras, of the arid ones, as well as from a great variety of toxic organic and chemical substances. </li></ul><ul><li>Spillages of oil (black tides) The accidental unloads and on a large scale of liquid oil they are an important reason of pollution of the coasts. The most spectacular cases of pollution for raw(unripe) are in the habit of being at the expense of the superoils used to transport them, but there are other many ships that spill also oil, and the exploitation of the petriliferous marine platforms supposes also an important contribution of spillages. It thinks that of every million embarked tons of crude oil a ton is spilt. Between the major black tides registered up to the moment they find the produced one for the petroleum Amoco Cádiz opposite to the French coasts in 1978 (1,6 million barrels of crude oil) and the produced one for the petriliferous well Ixtoc I in the gulf of Mexico in 1979 (3,3 million barrels). The spillage of 240.000 barrels for the petroleum Expón Valdez in the Princ. William Sound, in the gulf of Alaska, in March, 1989, produced, in the space of one week, a black tide of 6.700 km2, that put in danger the wild life and the fisheries of the whole area. </li></ul>
  8. 9. Images of the pollution of the water If you look you were observing since we are our environment. Ojala that on having seen this you think over .
  9. 10. The potabilizacion of the water of sea <ul><li>Other one of the practical applications of the solar power is the water potabilización. By means of the diverse variants of this technology it is possible to produce drinkable water from contaminated water. This can be achieved by means of relatively simple technology, this application turns out to be specially useful for regions removed from the comforts of the civilization, as islands and coastal little communicated regions. But also they can find applications technical and economically feasible in other places. </li></ul><ul><li>Depending on the degree of pollution that contains the water, diverse solar technologies exist for his purification. In general, the solar systems for the water purification are capable of removing only relatively small quantities of pollution, with exception probably, of that they are in use for purifying water of sea. The solar distillers, so, are not adapted to purify either black waters or industrial residues. There are adapted for potabilizar superficial waters , underground waters or water of sea. Basically there would be necessary to consider two levels of pollution for which are suitable: 1) Water Waters down with microbial light pollution and 2) with pollution of you go out disueltas. </li></ul>
  10. 11. You were observing some images of since potabiliza the water of sea <ul><li>Since podras to observe in the image, it is possible to see of that all that has a process in which him(her) one adds many elements to purify it </li></ul>
