Stop Breathing… or Die The earth’s atmosphere is a constantly moving body of gases that encircle our planet. This body of gases known as air is a mixture‚ not a chemical combination‚ of a number of gases; that is‚ each gas retains its own characteristic properties. It consists of about 78 percent nitrogen; 21 percent oxygen‚ and carries along with it water vapor‚ clouds‚ dust‚ smoke‚ soot‚ and a variety of chemical compounds. The remaining one percent contains all the other gases including carbon

light is gold over the city and Weschler (666) describes the LA afternoon light as a golden pink kind of light that comes about as a result of the combination of smog and bright white sunlight. This combination gives the area its unique configuration (color)‚ optical illusions‚ obstructions and at times objects do not produce shadows. Smog in the LA air too comes about too as various factors come together. Firstly‚ Weschler (668) discusses how the warm desert air traps the cool misty air brought in

Statement: To inform my audience about diesel emission technologies. Central Idea Statement: There has been three major technologies added to diesel exhaust systems since 2003 including an EGR‚ DPF‚ and SCR that have dramatically reduced NOx emissions (smog gases). Introduction I. Who knows the fundamental difference between a gas and diesel engine? A. A gas engine uses spark to ignite gasoline while a diesel engine uses compressed air to ignite the diesel fuel. II. Diesel engines in turn
