understand how an increase in greenhouse gases results in an enhanced greenhouse effect and that this may lead to global warming and consequences.
-enhanced greenhouse effect caused by pollution such as CO2, CH4 (methane) and water vapour- GREENHOUSE GASES.
- gases increase concentration- cons= infrared light from the planet reemitted backwards towards the earth rather than escaping into space.
- global warming- increase in average temperature.
Consequences
-melting of ice caps in polar regions= more water in oceans (raised sea levels) so there is a:
-chance ocean currents
-chance in which the wind is generated.
-lead to larger picture- climate change
-raising the average global temp- result in changes in the distribution of the worlds biomes (major vegetation in the worlds ecosystems)
great set of notes well done.
