Another pollutant associated with climate change is sulfur dioxide‚ a component of smog. Sulfur dioxide and closely related chemicals are known primarily as a cause of acid rain. But they also reflect light when released in the atmosphere‚ which keeps sunlight out and causes Earth to cool. Volcanic eruptions can spew massive amounts of sulfur dioxide into the atmosphere‚ sometimes causing cooling that lasts for years. In fact‚ volcanoes used to be the main source of atmospheric sulfur dioxide; today people

surfaces radiate the heat back into the air where all the greenhouses of the gases absorb at least some heat. 5. The variations in the intensity of the sunlight can cause temperature differences on Earth’s surface because of the concentrated sunlight of the equator which makes the surface warm and at the higher latitudes‚ where of course the sunlight spreads over a way larger and the area of the surface is at a cool temperature. 6. The process of conduction is the transfer of the energy as the heat

As population grows‚ drinking water becomes one of the most valuable resources in the world nowadays. The drinking water even becomes an important public health issue in some developing countries such as China and some African countries. During the entire process of drinking water treatment‚ the step of sterilization is especially important. The reason is that the raw water contains many kinds of microbes‚ which may results in spread of infectious diseases. This paper will show some sterilization

As sun rises‚ a light of beam through roof-box Describe what happens to the Sundagger on the solstices and equinoxes. At the winter and summer solstice‚ and rise also at the equinoxes‚ sunlight shines between three giant rocks at the summit of Fajada Butte‚ throwing bright “sundaggers” onto an

is significantly higher in the grassland than inside the forest. The causes of variation are mostly due to their difference in biotic components present. Forests have tall trees and layers of canopy that can intercept both sunlight and wind. Due to the blockage of sunlight by ____‚ the forest’s interior received only 26.18 lux while the grassland received 1028.7 lux. The colder air and soil temperature of the grassland can be attributed to the rainy weather condition at the date and time of

process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis provides the base for the one way flow of energy through the biosphere. Plants convert energy from the sun into sugars‚ which provide fuel for themselves and for other organisms. Photosynthesis also cycles carbon and oxygen nutrients through the biosphere. Producers are organism that can capture energy from sunlight or chemicals and use it to produce its own food from inorganic

When placed into a purpose-built hole in the roof‚ the homemade bulb refracts and spreads sunlight‚ illuminating the room beneath. Today‚ the project has expanded to more than 15‚000 solar bottle bulbs in 20 cities and provinces‚ benefiting more than 200‚000 families. It aims to reach 1 million beneficiaries by 2012.

temperature of about 100oC for a short period of time. Water heated to temperatures below 100C is generally referred to as pasteurized water. * Solar ultraviolet water disinfection‚ known as SODIS‚ is a method of disinfecting water using only sunlight and plastic bottles (PET bottles). This is an effective and very cheap method. SODIS is usually applied at the household level. Due to the fact that it is an affective and cheap method it is applied in numerous developing countries.
