solids or liquid droplets, in a gas. As such, clouds, smog, smoke, air born dust, etc. are all aerosols. About 90% of all aerosols are naturally produced . They can either be directly emitted into the atmosphere (primary aerosol like dust, sea salt and black carbon), or they can be formed in the atmosphere by condensation (secondary inorganic aerosol such as sulfates, nitrates and ammonium). Aerosols are argued to be cooling the surface of the earth. This is relevant because the effects of aerosols may

10/23/2012 The Green Movement There have been many movements in time but the green movement is the most important movement in time. The green movement is to educate people how to live a life more dependent on natural resources and to seek energy from cleaner sources other then harmful energy choices. There are many long-term effects of going green. For example, improved health, cleaner water, climate change, economic benefits (Duggan 1). There are also negative long-term effects of not going

1. If on the subject of climate change with another person and that person mentions that climate change is a natural cycle and not caused by humans, I would somewhat have to agree with them. I would agree with them that climate change is a natural cycle, but humans are very much so influencing it. In fact, I would point them to Katherine Hayhoe’s YouTube series where she talks all about it. She mentions in the videos that the climate does go through cycles of colder and warmer temperatures, but because

Global warming is the rise in the average temperature of the Earth’s atmosphere and oceans. Since the late 19th century, scientists have been warning the world that due to the increase of greenhouse gases in the Earth’s atmosphere, it is causes the Earth to undergo changes that are not good for humans or the planet. Some these increases are being caused by human activities such as burning of fossil fuels and deforestation. The Earth’s temperature had increased 0.8 degrees Celsius over the past 100

Coriolis effect What is the Coriolis effect? Produces Coriolis effect force Attalah that affect the moving object on the surface of the rotor, such as the Earth. Has been described this effect for the first time in 1835 by the French scientist Gustav - Gaspard Coriolis. Affect Attalah force on the left side to the direction of motion, for the movement of rotation in a clockwise direction, and on the right side, for the movement of rotation in the counter-clockwise direction. The Coriolis effect

“Green energy, our planet needs you” The Earth is our home, but it has been contaminated. Scientifics are concern with our planet which is dying everyday. It is our responsibility to take care the planet. The temperature has increased since the middle of the 20th century as a result of increasing concentrations of greenhouse due to human activity. As a consequence of the global warming many ecosystem are affected, has created climate variation, and many health diseases in the population
