The Earth’s atmosphere has changed over billions of years‚ but for the past 200 million years it has been much as it is today. We are‚ however‚ causing our atmosphere to change by human activity. Burning fossil fuels and deforestation are two examples of human effect on the environment. Composition of the Earth’s atmosphere The composition of air You need to know the proportions of the main gases in the atmosphere. The Earth’s atmosphere has remained much the same for the past 200 million years

place two pieces of metal in water‚ and apply electricity‚ the water separates into it’s basic molecules‚ Hydrogen and Oxygen (H2O). If you look at the picture on the left‚ you will see H2O molecules connected together in their liquid form which is WATER But when you apply electricity (from your car battery)‚ the molecules separate and form a GAS (called HHO) which is a mixture of Hydrogen and Oxygen. This HHO GAS is then sucked into your engine and mixed along with the air from the air filter

compounds from refined petroleum products such as gasoline or petrol‚ jet fuel‚ kerosene‚ diesel fuel and fuel oils. It’s important because removing the sulfur is to reduce the sulfur dioxide emission resulting from using those fuels in automotive vehicle‚ aircraft‚ railroad locomotives‚ ships or oil burning power plants‚ residential and industrial furnaces and other forms of fuel combustion. Another example why hydrodesulfurization is important is because removing sulfur from the intermediate product

sediments and from within the Earth has concentrated and modified these materials into valuable energy sources for it human purpose. Fossil fuels currently provide about 90 % of all technological energy used in the world. They provide the power to move vehicles‚ heat living spaces‚ provide light‚ cook our food‚ transmit and process information and carry out a wide variety of industrial processes (Thomson). There are countless marvels and miracles that we can list that came from the dawn of industrialization

calcium cations that are present in both water and plant cells. 2.)For farmers‚ soil acidification on their land can be a major problem. What is soil acidification‚ how is it caused and how is it prevented? Soil acidification is the build up of hydrogen ions(H+)‚ reducing the pH‚ therefore the soil becomes too acidic. The donor can be an acid‚ such as nitric acid and sulfuric acid.The addition of the acids can be due to acid rain and pollution. Many nitrogen compounds‚ which are added as fertilizer

Vehicle Extrication communication Vehicle Extrication is the systematic removal of the parts of a vehicle that has been involved in a crash from around the driver and occupants. It has been developed into a process or system over they years to ensure the safety of the rescuers and victims‚ and to improve the chances of victim survival. The basic steps to vehicle extrication are scene size up‚ vehicle stabilization‚ glass removal‚ gain access‚ disentanglement‚ victim removal‚ and breakdown/cleanup

What is hairspray made of? Hairspray is a solution of long‚ chainlike molecules (called polymers) in a very volatile solvent. Spraying deposits a stiff layer of the polymer on your hair after the solvent evaporates. The solvent used was once a compound of carbon‚ fluorine‚ and chlorine (a chlorofluorocarbon‚ or CFC). CFCs are nontoxic‚ nonflammable‚ and make almost ideal aerosol propellants. But when it was learned that they causedestruction of stratospheric ozone‚ they were replaced with other

Alternatives to Gasoline in Vehicles One of the most pressing issues in today’s society both climatically and economically is the use of gasoline and fossil fuels in our vehicles. Ever since the creation of the automobile in the early 1900s gasoline has become a commodity that helps the global economy tremendously. However‚ after over one hundred years of the use the resource has come to be scarcer‚ and all of the greenhouse gases and pollution that were released have helped set in motion the
