it is a summary of the topic about t6he atmosphere..... all information written are not words of the maker but are compilations only from various book,journal,internet sources... this makes learning about the atmosphere for freshmen easier,,,

1. Meteorology Deals with the study of climate and weather. Is the study of the changes in temperature, air pressure, moisture, and wind direction.

8. The word troposphere comes from tropein, meaning to turn or change. All of the earth's weather occurs in the troposphere. Increased temperature because of the ozone in this layer that absorbs Uv radiation from the sun. Mesosphere - Its teperature reaches 100 degree celcius. A layer which contains a fraction of the atmosphere mass.The temperature is too high that allows molecules to move at speed. Ionosphere - A region in the atmosphere where Ionization takes Place. Exosphere- Is the outermost layer. The hottest. Collision of particles is very rare.

21. Radiation is the transfer of heat energy without the involvement of a physical substance in the transmission. Radiation can transmit heat through a vacuum. Energy travels from the sun to the earth by means of electromagnetic waves. The shorter the wavelength, the higher the energy associated with it. This is demonstrated in the animation that I will be showing on the next slide.. As the drill's revolutions per minute (RPMs) increase, the number of waves generated on the string increases, as does the oscillation rate. The same principle applies to electromagnetic waves from the sun, where shorter wavelength radiation has higher energy than longer wavelength radiation.

33. Wind Belts There are two types of winds: 1. Local wind 2. Prevailing wind Wind Belts – circle the earth and play an important role in the weather and climate. Prevailing Westerlies – wind Blowing for the direction from west Prevailing Easterlies Winds Blowing from East. Winds we usually encounter. Blow from the same direction and often travel long distance.
