CLIMATE

  1. LATIDUDE
  • Latitude is the distance form any point on earth to the Equator.
  • Latitude determines the level of insolation at any point. Insolation is the amount of solar energy received. As we move further from the Equator insolation is less intense.
  • Latitude determines the main climate zones:
    • Tropical zones: from tropic of cancer to trpic of capricorn. There are high temperatures and abundant precipitation.
    • Temperate zones. Temperatures vary depending on the season and prcipitation is more abundant in areas near the sea.
    • Polar zones. Very low temperatures and low precipitation.
  1. ALTITUDE
  • Is the heigth of a place relative to sea level.
  • Temperature falls 0.6º for every 100 m
  • Relief can also cause precipitation when it causes moist air to rise and condense.
  1. DISTANCE FROM THE SEA
  • In coastal areas, temperatures are mild all the year. This is so beceause the seas and oceans regulate temperature
  • There is also more precipitation near the sea.
STRUCTURE OF THE ATMOSPHERE
  • Exosphere: transitional zone between atmosphere and space. Gasses lose chemical properties and dispense until their composition is like the space.
  • Thermosphere: high temperatures up to 1000ºC. This layer includes ionosphere where aurora boreails occurs.
  • Mesosphere: Coldest layer of the atmosphere with low air density.
  • Stratosphere: Air is strafied and stable. Ozone layer wich absorbs ultraviolet radiation from the Sun is located here, between 20-40km above the Earth.
  • Troposphere: is the lowest layer. Most air we breathe is found in the first 6km of the troposphere main meteorogical phenomean occur in this layer.
