Global Warming Flashcards
Explain the Greenhouse Effect.
The sun transfers energy to the earth as radiation. The earth absorbs the radiation and the re-emits it as infared and some of the infared radiation gets absorbed by greenhouse gas molecules. Energy is now trapped in the atmosphere making the temperature rise.
Increase of temperature could lead to..
Extinction of species, Ice caps melting and the migration of people because of drought/flooding
The human population increasing from 1 billion to 7 billion people could lead to..
We will need more recources and more land so we would cut more trees down which could lead to deforestation.
How is methane released?
Methane is released by cattle passing air also when growing rice in paddy feilds, This will cause a rise in temperature.
Sea levels rising could cause…
People at risk of being in a flooded place meaning people will need to migrate and organisms may loose their habitats.
Habitat loss could lead to…
People are using more and more land and then animals wont have anywhere to live as a result they may not survive which could make their species extinct furthermore if that species goes extinct then their consumer may not be able to survive and then will die out.
Natural disasters could lead to…
Increased temperatures, risk of wildfires and increase in sea levels could lead to risk of tsunamis.
