  • Climatic mechanism
    1. Action of the Sun on our planet
    2. Solar radiation sending varying energy based on the angle
    3. Greenhouse effect trapping part of the hot radiation of the Sun
    4. Energy reflected back to space called albedo
  • Greenhouse effect
    Makes it possible to trap part of the hot radiation of the Sun, preventing much lower temperatures with great variation between night and day
  • The heat from the Sun is preserved in ocean water and air masses
  • Rotation of the Earth and changes in inclination of the Earth on its axis
    Put in motion air and water masses, leading to temperature exchanges between north and south
  • Composition of the atmosphere
    Allows part of the heat provided by the sun to be naturally preserved, creating a natural greenhouse effect
  • If the density of the atmosphere decreases (due to altitude), the capacity to conserve heat decreases, explaining why it is colder in high mountains (average loss of 1°C/160 m)
