air - Coggle Diagram

- - - - signals/radio waves sent from earth reach to this ionosphere and reflected bach to earths receiver
  - - - most suitable to fly aeroplanes
  - - - and this heli and hydro escape into space
  - - - most imp layer of atmo
- - - - temp varries from day to night a.w.a season to season
    - - isolation is def as condi where sun energy comes in contact with earths surface
      - this isolation is maximum at equator and decrea towards poles
        
        as a reult temp at eqa is maxi and towards poles decres
      - isol decres distri temp decre ex: towards poles
      - isola is more means distri temp is more ex: equator
    - - either in vill or cities the roads building say whole envi heated up in the morning and this tempereature is released at night
      - vill are mostly open areas so heat is released easily and temp downs
      - cities mostly have high raised buildings the warm air is struck b/t buildings and heat circultates in atmo rather than releasing so they are hot
  - - - if temp is high on area(land)
        
        air warms up in this place
        
        as a result air expand and its density decreases
        
        now this low dwnse air automatically flow up(atmosphere) and low pre area is created on land
        
        now air on top with heavy density will sink on to land by creating high pressure areas
        
        due to this reason pressure at water bodies is high than land
        
        and vise-versa
        
        becau temp at water bodies less than od land
- - - - and in equal ammount plants take this carbon
      - this way co2 balance in atmos
      - human, ani release carbon
      - but if we burn fossil fuels co2 is increased causing global warming and making life diffi
        
        when co2 incre temp increses
        
        this incre intemp is called global warming
        
        this may cause natu disas like floods and huge damage
      - imp:
        
        co2 is a green house gas and its contribution in green house effect is huge
        
        green house effect
        
        usually sun rays tend to falls on earth but some rays reflected back into spce without faling on earth
        
        if this happens for very long time the temp on eaarth will be very cold due to less presence of suns heat and light
        
        and in such cold situa life is diffi
        
        this green hou gases will trap heat from sun and release them into atmo and this keeps earths surface warm and supports life
        
        this effect is known as green house effect
  - - - animals
        
        ani take some ammount nitro into lungs durig inhalation but we exhale it immediately as we dont need nitro for our body functioning
      - plants
        
        plants need nitro for their survival
        
        they cant take this nitro directly from air
        
        and they this nitro through some bacteria present in soil
        
        example
        
        bacteria: rhizobium
        
        this process of convert atmo nitro into ammo is called nitrogen fixation
        
        rhi converts atmospheric nitro in soil into ammonia
        
        plants can absorb this ammonia from soil
        
        other bacte
        
        convert ammonias into nitrates
        
        this pro called nitrification
        
        in this form also plants can absorb nitrogen
    - - humans and ani take oxy dire from atmos
      - pla release oxy directly through photosynthesis
      - this way oxy content is balanced in air
      - if we cut trees oxy levels may drop further complicating survival
