Global Warming The greenhouse effect‚ in environmental science‚ is a popular term for the effect that certain variable constituents of the Earth ’s lower atmosphere have on surface temperatures. It has been known since 1896 that Earth has been warmed by a blanket of gasses (This is called the "greenhouse effect."). The gases--water vapor (H2O)‚ carbon dioxide (CO2)‚ and methane (CH4)--keep ground temperatures at a global average of about 15 degrees C (60 degrees F). Without them the average

human health‚ air pollution can cause a variety of environmental effects: Acid rain is precipitation containing harmful amounts of nitric and sulfuric acids. These acids are formed primarily by nitrogen oxides and sulfur oxides released into the atmosphere when fossil fuels are burned. These acids fall to the Earth either as wet precipitation (rain‚ snow‚ or fog) or dry precipitation (gas and particulates). Some are carried by the wind‚ sometimes hundreds of miles. In the environment‚ acid rain damages

global warming‚ people [humanity] can implement the solutions to deal with the effects of it on the international‚ state and personal levels. Global warming is commonly referred to as an increase in the temperature of the lowest layers of Earth’s atmosphere. Global warming has occurred in the distant past as the result of natural influences‚ but the term is most often used to refer to the warming predicted to occur as a result of increased emissions of greenhouse gases. Primary greenhouse gases include

of plants called (transpiration). But this water doesn ’t just disappear; it ’s absorbed into the atmosphere and carried around the world by currents of air. Eventually the water in the air condenses to form clouds‚ which return it to Earth as rain or snow. The water that collects on land flows back to the oceans in rivers or streams-to begin the cycle all over again. This interaction between atmosphere and ocean is what gives us our weather and climate which is known as Atmospheric Circulation/Convection

AQUA SILENCER SYNOPSIS This project is an attempt to reduce the toxic content of diesel exhaust‚ before it is emitted to the atmosphere. This system can be safely used for diesel power packs which could be used in inflammable atmospheres‚ such as refineries‚ chemicals processing industries‚ open cost mines and other confined areas‚ which demands the need for diesel power packs. WORKING PRINCIPLE The aqua silencer is more effective in the reduction of emission gases from the engine exhaust gas

Sea level Global warming is effecting the Bahamas by raising the sea levels of the ocean‚ which will cause there to be less land that actually makes up the Bahamas. This can actually make all of the Bahamas a smaller country because more land is being put under water to the rising sea level‚ Warmer ocean temperatures are also now understood to cause coral bleaching. Rising levels of carbon dioxide (greenhouse gas emissions) are also decreasing the pH level of the ocean‚ known as ocean acidification

The greenhouse gases and the resulting greenhouse effect are important. If the greenhouse gases were not present in the atmosphere‚ our Earth would be an icebox. We would have climate similar to that in Mars. The average temperature on Earth would have been about -18 degrees Celsius‚ which is below the freezing point of water. If this was the Earth’s temperature‚ there would hardly be any liquid water on Earth and life as known today would not be possible. Therefore the greenhouse effect is important

Country Where is the best place to raise a child‚ in the city or in the country? I would rather live and raise my family in the country‚ because of the clean environment‚ peaceful atmosphere‚ and smaller schools. My primary reason for choosing the country instead of the city is the clean environment. The air smells fresh and clean‚ because there are less cars creating pollution. In the city‚ there are busses‚ taxis‚ and cars on all the streets contributing harmful chemicals into the air. While

Global warming is the term used to describe a gradual increase in the average temperature of the Earth’s atmosphere and its oceans‚ a change that is believed to be permanently changing the Earth’s climate. Even though it is an ongoing debate‚ it is proved by the scientists that the planet is warming. The 29th century is experiencing a continued increase of Earth’s mean atmospheric temperature by about 1.4 degrees F and about two thirds of it occurring since 1980. This is global warming is affecting
