For example?
infra red radiation
7 of 21
However some long wavelength radiation interact with what molecules?

WHAT HUMAN ACTIVITY CAUSES CO2 TO RISE?
-------------------------------------
What are 4 causes?
agriculture
waste
burning fossil fuels
deforestation
12 of 21
How does burning fossil fuels cause it?
when burnt the carbon locked up in the fuels are released as C02
13 of 21
Deforestation since when they are ____ all the CO2 that was _______ via _________ is released back out?
when they are cut all the CO2 that was absorbed via photosynthesis is released back out
14 of 21
Agriculture since an _______ in the demand of _____ e.g. beef means more ______ must be _____ and they produce _______ which is a _____ ____?
an increase in the demand of meat e.g. beef means more cows must be farmed and they produce methane which is a greenhouse gas
15 of 21
Waste since it ends up in ______ ______ and will _____ and release a lot of ___ and ____?
landfill sites and will decompose and release lots of CO2 and methane
