Deforestation In Brazil Essay

In one of the major regions of deforestation, the province of Rhondonia, Brazil,the rainfall has been severely and or completely stopped. Theory: As thetropical rainforest of Rhondonia, Brazil is leveled for farmland, rainfall issignificantly and directly reduced. Rainfall is reduced because there are fewertrees to return water vapor to the air through tree transpiration, or waterevaporation through trees. Relative humidity is the amount of water vapor in theair compared with the amount of vapor needed to make the air saturated at theairs current temperature.

The point past saturation is precipitation, orrainfall. If deforestation is the cause of decreased rainfall, then decreasedaverage relative humidity will be evident. Experimental Design: In order, toisolate deforestation as the primary factor causing decreased rainfall, testswill be conducted to measure relative humidity. A sling psychrometer will beused to gain these measurements. http://www. taftan.

com/thermodynamics/HYGROMT. HTMIt is used to measure the amount of moisture in the air. The dry-bulbthermometer measures the air temperature, and the wet-bulb measures the lowesttemperature that can be obtained by evaporating water into the air at constantpressure. A calculator will be used to convert to relative humidity.

MillibarsInches of Mercury Relative humidity measurements will be taken every day for oneyear.

The measurements will be taken at different stations in the rainforest. Four stations will be located no further than 10 miles from current areas ofdeforestation. Four other stations will be located at the interior of therainforest, and at least 50 miles from recent deforestation. After thesemeasurements are taken, they will be analyzed in three different ways.

RunExperiment: The daily measurements were tracked for one year. Comparison 1 – Therecent relative humidity measurements of the rainforest will be compared toprevious figures of relative humidity. The average off all relative humiditymeasurements will be compared to the relative humidity of the rainforest beforethis experiment. Comparison 2 Recent relative humidity measurements ofdifferent regions of the rainforest will be compared. Measurements from areasnear to sites of deforestation will be compared to measurements from sitesfurther from areas of deforestation. Comparison 3 Measurements towards theend of the study will be compared to measurements at the end of the study.

Average relative humidity measurements for the first month of the study will becompared to the average from the last month. Analysis: Comparison 1 – Taking theaverage of all measurements and comparing it to the average relative humidityfrom the prior year it was found that the average relative humidity had droppedone percent. Comparison 2 Taking the average of each stations relativehumidity, it was found that all stations within 10 miles from deforestation hadan average of two percent lower that stations at least 50 miles fromdeforestation. Comparison 3 Taking the average relative humidity for thelast month from all stations and comparing it to the first months average it wasfound that the average had dropped . 5 percent over the year. Conclusion: Thefindings suggest that deforestation is affecting the amount of rainfall inBrazil.

The deforestation will not only continue to affect rainfall but willlead to increased global warming as evaporative cooling decreases. Evaporativecooling takes place when solar energy, or heat, is used to convert water fromtrees to water vapor or humidity.Environment .
