Geography 3.6 | Analyse aspects of a contemporary geographic issue | A contemporary geographic issue refers to a topic‚ concern‚ problem‚ debate‚ or controversy related to a natural and/or cultural environment‚ which includes a spatial dimension‚ and is currently unresolved. The deforestation that is currently occurring in Africa is a contemporary geographic issue‚ as it is a concern for the African environment‚ covering the region of sub-Saharan Africa‚ and is still on-going in the present

Millions of trees are cut down just to make workbooks and textbooks for schools. While students continue to have back pains at early ages‚ the technological revolution has developed compact‚ light‚ laptops; some weighing as little as two pounds. Will we continue to place strain

Hydraulic fracturing‚ otherwise known as fracking‚ is a technique used to stimulate the production of oil or gas. While fracking has aided in the plumpting of gas prices across the United States‚ it unfortunately causes serious health and environmental issues. Contaminated water‚ contaminated soil‚ polluted air‚ exposure to toxic chemicals and long term health effects. Fracking brings more harm than good. Fracking is accomplished when a well with veins (small branching off pathways)‚ is drilled

UniversityMechanical Engineering at Pune University ABSTRACT Sensotronic Brake Control- also known as Brakes of the future is appellation given by Mercedes to an innovative electrically controlled brake system which operates more precisely than a conventional hydraulic braking system. Within no time you press the brake pedal and the sensor identify situation in hand‚ the microcontroller makes an exact calculation of brake force necessary and distributes it between the wheels as per the current scenario. This allows

A principle concern in the fracking debate lies over the content of the “fracking fluid.” This fluid is used to increase pressure in shale formations and cause fractures that increase permeability and allow greater access and capture of liquid natural gas or other hydrocarbon products that would be otherwise inaccessible or require numerous more wells be drilled (He‚ Li‚ Liu‚ Barbot‚ Vidic‚ 2014). This fluid consists of water and chemical additives such as‚ “ friction reducers to optimize flow characteristics

There is nothing fictitious about the arguments in fracking. Hydraulic fracturing‚ also known as fracking‚ is a way of obtaining oil and gas through the practice of cracking open rocks at high pressures using water‚ sand‚ and various chemicals (Jackson‚ 2016‚ para. 1). All over America‚ numerous interest groups participate in a continuous debate on the ethics of this procedure. Two prominent documentaries that circulate the media are FrackNation by Phelim McAleer and Gasland by Josh Fox. Each

currently estimates that two thirds of this natural gas was extracted from the ground using a process known as hydraulically fractured. This is when hydraulic fluid is injected under high pressures into wells deep underground in order to cause the underground rock formations to fracture and release natural gas deposits. The process of hydraulic hydraulic fracturing has been used to extract natural gas since the 1940 advancement in technology has allowed it to become much more effective and profitable

Mineral oil is most commonly put to use in our daily lives as baby oil‚ which has a fragrance added to it. It is clear‚ odorless and colorless. It is formed as a by-product during the distillation of petroleum from crude oil‚ to produce gasoline and other petroleum-based products. It is produced in very large quantities and is inexpensively available in drug stores. Due to its easy availability and low value‚ it is put into use in a wide range of avenues. As a Laxative Doctors often recommend

beeps for around one second if the brake system is intact. If the brake fails‚ the red LED glows and the buzzer stops beeping. The circuit will work only in vehicles with negative grounding. It also gives an indication of brake switch failure. In hydraulic brake systems of vehicles‚ a brake switch is mounted on the brake cylinder to operate the rear brake lamps. The brake switch is fluidoperated and doesn’t function if the fluid pressure drops due to leakage. The fluid leakage cannot be detected easily

The central argument of the film is that there is a risk caused by contaminated drinking water from ground water sources which tends to be a result of hydraulic fracking. All water is connected so if an individual or company pollutes an area where the water is‚ the water will inevitably become polluted over time as well. This argument is effective mostly due to the fact that the film showed that the government and large cooperations were getting away with being responsible for causing health concerns
