Chemistry Of The Atmosphere Flashcards
How much of nitrogen is In the atmosphere
80%
How much oxygen is in the atmosphere
20%
What do volcanoes produce
Nitrogen which gradually builds up in the atmosphere there is also small proportions of methane and ammonia
What do the oceans form
C02 dissolved in the water
Why do algae and plants produce
Oxygen which is now in the atmosphere by photosynthesis
Equation for photosynthesis
6CO2 + 6H20 —> C6H12O6 +6O2
What is C6H12O6
Glucose
What do algae and plants decrease
The percentage of co2 in the atmosphere by photosynthesis
How was c02 decreased
By the formation of sedimentary rocks and fossil fuels in which contained carbon
What do ghg in the atmosphere do
Maintain temp on earth high enough to support life
Name 3 ghgs
Water vapour , co2 , methane ,
What human activities inc yeh amounts of ghg in the atmosphere
Co2
Methane
What is the carbon footprint
Is the total amount of co2 and other ghg emitted over full life cycle of a product service or event
How can the carbon footprint be refuved
By reducing emissions of co2 and methane
How does the combustion of fuels relate to the atmosphere
It’s a major source of atmospheric pollution
