Chapter 7 the atmosphere

1. The atmosphere protects us from dangerous things from space
2. air quality is poor
3. improving air quality is important
4. the atmosphere is made of many different gasses

1. properties of air are density and pressure
2. measuring air pressure tools

   Anotações:

   • mercury barometers, aneroid  barometer,
3. altitude affects air pressure and density

Anotações:

• thermosphere, troposphere, stratosphere, mesosphere

1. energy from the sun

   Anotações:

   • visible light, non-visible radiation
2. energy in the atmosphere

   Anotações:

   • Some sunlight is absorbed or reflected by the atmosphere.
3. Energy at earth surface

   Anotações:

   • When earths surface is heated, it radiates most of the energy back into the atmosphere as infrared radiation

1. thermal energy and temperature

   Anotações:

   • heat is measured with a thermometer in degrees of celcius or farenhight
2. how is heat transfered

   Anotações:

   • radiation conduction convection heating the troposphere

1. what is wind

   Anotações:

   • winds are caused by differences in the air pressure. 
   • wind is measured by a anemometer
   • wind chill factor makes you colder than the actual temprature
2. local wind

   Anotações:

   • sea breeze, land breeze
3. global winds

   Anotações:

   • global convection currents the coriolis effect
4. global wind belts

   Anotações:

   • doldrums horse latitudes trade winds prevailing westerlies polar easterlies jet steams
