Atmosphere and Air Temperature

Atmosphere and Air Temperature

• The hottest parts of Earth are the areas near the
  equator, while the coldest areas are around the
  North and South Poles.
• Combining the words incoming, solar and
  radiation forms the term insolation.
• The greater the angle of insolation, the warmer a
  place will be.
• The angle of insolation at different times of the
  day changes the length of shadows.
• In the same light, dark colored materials get
  hotter than light colored materials.
• A rough surface gets warmer than a smooth surface
  because it absorbs more energy.

Atmosphere and Air Temperature

• The troposphere is the lowest layer of the
  atmosphere.
• As you go higher in altitude, air pressure falls
  (decreases).
• Normal air pressure is greatest at sea level.
• 99 of the air we breathe is a mixture of
  nitrogen and oxygen. Air also contains water
  vapor and dust particles.
• Weather really describes what conditions are
  like in the troposphere at any given time and
  place.
