    Global Atmospheric Circulation This essay will describe patterns of atmospheric heating and circulation. When the surface air reaches the Equator‚ it gets heated and rises to the top of the troposphere‚ where it spreads back toward the poles. When it gets to the poles‚ it descends back to the surface again to complete the cycle. The heat of the Sun causes water to evaporate from lakes‚ rivers and oceans‚ as well as from the leaves of plants called (transpiration). But this water

    * What is the greenhouse effect‚ and how does it work? The greenhouse effect is when the short wave lengths of visible light from the son pass through a transparent medium. They are then absorbed but the longer wavelengths of the infrared re-radiation from the heated objects are unable to pass through that medium. The Greenhouse Effect is when there are various gases in the atmosphere‚ such as carbon dioxide and even water vapor that traps the sun ’s energy‚ or heat‚ inside. When unable

Most barometers use mercury in a glass column‚ like a thermometer‚ to measure the change in air pressure. I came up with this idea from when I read in a book about how some kids tried to

This was due to pipetting error; the tip of the pipette did not touch the liquid (TE) in the micro-centrifuge‚ so no DNA
