Greenhouse Effect - Coggle Diagram
Greenhouse Effect
1. What is greenhouse effect?
warming up of Earth
greenhouse gases = carbon dioxide, nitrous oxide, methane
real greenhouse
solar radiation/sunlight comes through glass
sunlight is stuck inside greenhouse
heats up air inside
nice warm & humid environment for plants
Earth's atmosphere
land, water, plants soak up most radiation
energy sent back to atmosphere as infrared radiation (heat)
greenhouse gases absorb and send heat back down to surface
heat loop
2. Consequences
x greenhouse gases
33 °C colder
too cold for us
greenhouse effect too strong
too hot
climate changes & environmental disasters
global warming
earth's average surface temp.
risen by 3/4°C in the last century
glaciers & polar ice caps melting
sea levels could rise
flooding coastline
habits of many plants, animals, ppl endangered
warmer temp.
dangerous to life botn in ocean & on land
3. Greenhouse effect & global warming
change weather patterns
↑ no. & severity of floods, droughts, storms (hurricanes)
scientists' prediction
temp. ↑ by 6°C in the next century
cause of global warming
skyrocketing levels of CO2 & methane
human activity
burning of fossil fuels
more CO2
deforestation
plants & trees absorb CO2 and produce oxygen
dependence on animals
cows and livestock produce methane
methane - 20 times more powerful than CO2
