The greenhouse effect is the rise in temperature caused by gases in the atmosphere

Extracts from this document...

Introduction

The greenhouse effect is the rise in temperature caused by gases in the atmosphere. Sunlight enters the Earth's atmosphere,. As it reaches the Earth's surface, the sun's energy is absorbed. Once absorbed, is sent back into the atmosphere, but much of it remains trapped in the atmosphere by the greenhouse gases, causing our world to heat up. This process is called the greenhouse effect. As energy from the sun passes through the atmosphere, a number of things happen to it. About a quarter of the energy is reflected back into space by clouds and particles. Some of the energy is absorbed by clouds, gases and particles in the atmosphere. Some of it passes through the blanket of greenhouse gases such as carbon dioxide, water vapour and methane and is: Used for processes such as photosynthesis, heating and melting The heating of the ground by sunlight causes the Earth's surface to radiate infra-red energy; a small proportion of this is reflected back into space. ...read more.

Middle

The now warmer atmospheric greenhouse gas molecules begin radiating infra red energy in all directions. Most of this is directed back to the Earth's surface where it once again is absorbed by the surface. The heating of the ground by the radiation causes the ground surface radiate again repeating the cycle. The greenhouse effect is essential in keeping the earth at a liveable temperature but humans have enhanced it through the burning of fossil fuel, etc. Alternative methods of energy production a must be used and energy use must be kept to a minimum if the temperature of the Earth's global temperature is to be maintained. Acid rain is rain, snow or fog that is polluted by acid in the atmosphere and damages the environment. The two gases which cause acid rain the most are sulphur dioxide (SO2) ...read more.

Conclusion

The acid can be neutralised by a base such as limestone. Acid rain damages the surfaces of leaves and needles reducing a tree's ability to withstand cold, and inhibit plant germination and reproduction. Consequently, tree vitality and regenerative capability are reduced. It also increases the concentration of aluminium in the soil, which interferes with the uptake of nutrients by the trees. Lack of nutrients causes trees to grow more slowly or to stop growing altogether. Acidic rain can also erode buildings, moments and other stone based structures. The emission of sulphur dioxide and nitrogen oxides must reduced in order to prevent damage to the environment. This again, like prevention of production of greenhouse gases can be prevented by using alternative sources of energy such as wind, nuclear and tidal power and sparing energy. Example of sparing energy are turning of lights in unused rooms, buying energy efficient appliances and taking public transport instead of a car. ...read more.

    Traffic density in Moscow is overall very dense with minor variation in summer, when most of the population drives to the countryside for leisure. This, however, does not result in significant reduction of NO2 concentration due to the smog issues (Gorchakov et al 2006; Mosecomonitoring 2010; Roshydromet 2010).
