THE GASEOUS PART OF THE EARTH
  1. The Earth's Atmosphere
    1. Composition

      Annotations:

      • - Dust Clouds - Gases: Carbon Dioxide 0.03 % - Water Vapour: from volcanic eruptions - Oxygen: from photosynhesis  21 % - Nitrogen: 78 % Additionally: - Gases and smoke from industry, cars, heating, etc.
      1. Structure

        Annotations:

        • - Exosphere: 700 km - Thermosphere: 80 km,    -- Ionosphere: 80-550 km. Relects radio and tv waves. - Mesosphere: 50 km. - Stratosphere: 12 km. Ozone - Troposphere: 0 km
        1. Function

          Annotations:

          • Regulates Temperature.
          1. Day/night differences

            Annotations:

            •  During Day: - Earth's surface absorbs some solar radiation and heats up. - The warm surface heats the nearest layers of air. - Some radiation is reflected and escapes. - Carbon dioxide and water vapour relects some radiation back to the Earth again. During Night: - The atmosphere stops the surface heat escaping into space. - Water vapour and carbon dioxide retain heat like the glass in a greenhouse.
            1. Unequal warming

              Annotations:

              • Depends on the latitude Depends on the inclination of Sun's rays.
          2. Atmospheric Pressure and Humidity
            1. Pressure

              Annotations:

              • - Is the ratio of the weight of the atmosphere to the area over which that weight is distributed. - Is a quantity - Unit: Pascal
              1. Humidity

                Annotations:

                • - Is the amount (volume) of water vapour in a specific amount of air. - Saturation point -
                1. Absolute

                  Annotations:

                  • Is the amount of water vapour in 1 m3 of air at a specific moment. Expressed in grams.
                  1. Relative

                    Annotations:

                    • Is the relationship, expressed as a percentage, between the present amount of water vapour in a volume of air and that which it could contain if the volume of air were saturated.
                2. Climate

                  Annotations:

                  • Influenced by: - unequal warming - masses of air with different degrees of humidity Refers to the main atmospheric phenomena in a specific region that occur every year. - Depends on latitude -expressed in term of temperature and rainfall
                  1. Atmospheric phenomena

                    Annotations:

                    • Occurs in the troposphere: Caused by the wind: - Hurricanes - Whirlwinds or dust storms - Tornadoes Related to the water vapour: - Clouds - Rain - Fog - Frost - Snow - Hail - Dew
                    1. Weather

                      Annotations:

                      • Refers to a series of atmosphereic phenomena that occur at a specific moment in a specific place. Scientific Instruments: - Thermometer - Barometer - Rain Gauge - Hygrometer - Weather Vane - Wind Gauge
