OXYGEN-CARBON CYCLE The carbon-oxygen cycles are actually two independent cycles. However‚ both these cycles are interconnected as well as interdependent on each other to some extent. There are four processes involved in the completion of the carbon-oxygen cycle. Oxygen-carbon cycle processes are: * Photosynthesis Plants undergo photosynthesis that helps them produce energy and food for themselves. During photosynthesis‚ plants take in carbon dioxide (CO2) and absorb water (H2O) with the help

Carbon tax A carbon tax is a form of carbon pricing. It is all about cutting the pollution and driving investment in cleaner energy sources‚ such as solar‚ gas and wind‚ along with new energy sources like geothermal and wave energy. Carbon taxes offer a potentially cost-effective means of reducing greenhouse gas emissions. They help to address the problem of emitters of greenhouse gases not facing the full (social) costs of their actions. Carbon taxes are a regressive tax‚ in that they disproportionally

Essay: “All research carried out in the past 50 years has proved that smoking is harmful for passive and active smokers alike. A ban on smoking in all public places with immediate effect is therefore the only reasonable option.” Did you ever deeply inhale the cold cloud of smoke of someone standing in a public place? Every one of us faces these situations to a greater or lesser extent. No matter if it happens indoors or outdoors‚ non- smokers never benefit from it. The question is‚ why smokers

Strontium Manganese Oxide Introduction The ternary inter oxide SrMnO3 was first characterized by XRD by Negas and Roth []. This perovskite type inter oxide crystallizes in the hexagonal form with the space group P63/mmC(194). This inter oxide is of considerable interest to materials scientists owing to its ability to accommodate a high degree of anion vacancies‚ crystal structure and its high Neel Temperature (TN). It also exhibits polymorphism with two different cubic and hexagonal structures
