formed. These volcanoes released various gases. Around 4600 million years ago the Earth’s atmosphere was made up of Carbon Dioxide‚ Water Vapour‚ Nitrogen‚ Ammonia‚ Hydrogen Chloride‚ Sulphur Dioxide‚ Hydrogen and the Noble gasses. There was no oxygen at this time. Oxygen only appeared in the atmosphere around 3500 million years ago when the first simple organisms began releasing it. Most of the Earth’s atmosphere (78.08%) now is made up of Nitrogen. Another 20.95% is mage up of Oxygen. A number of

are common components that make each version of the healthcare system a whole. The following will describe the basic service components and why they are necessary to make a healthcare system complete. The first of these basic components is Primary Care. Primary Care is defined as a basic level of health care provided by the physician from whom an individual has an ongoing relationship and who knows the patient ’s medical history. Primary care services emphasize a patient ’s general health needs

Historical Atmosphere Challenge The changes we are witnessing and those that are predicted are largely due to human behaviour. We are burning fossil fuels‚ and heating up the planet at the same time. We blow ever increasing amounts of carbon dioxide (CO2) into the atmosphere every year – 29 billion tonnes of it (2004) and rising – and this causes the temperature to increase.

Describe how atmospheric circulation gives rise to the formation of high and low pressure area? The origins of the creation of areas of differing pressures can be seen to start with the sun. As the sun gives off radiation some is absorbed by the earth‚ however this absorption is centred on the equator and therefore creates a disparity between the heat of the equator and tropics and the rest of the globe. Between 450 North and 300 South there is a positive heat budget whereas outside these regions

atmosphere of Earth is a layer of gases surrounding the planet Earth that is retained by Earth’s gravity. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation. A. Nitrogen - 78% - Dilutes oxygen and prevents rapid burning at the earth’s surface. Living things need it to make proteins. Nitrogen cannot be used directly from the air. The Nitrogen Cycle is nature’s way of supplying the needed nitrogen for living things. B. Oxygen - 21% - Used by all living things. Essential

The Concentration of CO2 in the Atmosphere Introduction Carbon dioxide (CO2) is a colorless‚ odorless‚ non-flammable gas that can be produced by cellular respiration and burning of fossil fuels. Many types of industries such as breweries‚ mining ore and the manufacturing of carbonated drinks‚ drugs‚ disinfectants‚ pottery‚ and baking powder; utilize the CO2 gas (Appendix C). Recently Scientist proposed a theory in which CO2 concentration levels above 450ppm will lead to dramatic and potentially

Seven Virtues versus Seven Sins Virtues are character strengths consistently applied to moral decision making. They show positive patterns of behavior. However‚ vices are negative patterns of behavior‚ often harmful to one’s self or others. The seven virtues are faith‚ hope‚ charity‚ prudence‚ justice‚ fortitude‚ and temperance. The seven deadly sins are pride‚ envy‚ gluttony‚ lust‚ wrath‚ greed‚ and sloth. Practicing one virtue can protect one from the temptation to perform an act which is sinful
