Studied by 2 people
Volcanic activity
________ also released nitrogen, which built up in the atmosphere over time, as well as water vapour and small amount of methane and ammonia.
Greenhouse gases
________ like carbon dioxide, methane and water vapour act like an insulating layer in the Earths atmosphere.
Deforestation
________: fewer trees means less CO2 is removed from the atmosphere via photosynthesis.
water vapour
When the ________ in the atmosphere condensed, it formed the oceans.
Agriculture
________: more farm animals produce more methane through their digestive processes.
fossil fuels
Burning ________: carbon that was locked up in these fuels is released.
forms of human activity
Some ________ affect the amount of greenhouse gases in the atmosphere.
Green plants
________ and algae evolved and absorbed some of carbon dioxide so that they could carry out photosynthesis.
carbon dioxide
As well as absorbing the ________ in the atmosphere, green plants and algae produced oxygen by photosynthesis, this is when plants use light to convert ________ and water into sugars.
Earths temperature
The ________ varies naturally, but recently the average temperature of the Earths surface has been increasing.
Deforestation
fewer trees means less CO2 is removed from the atmosphere via photosynthesis
Burning fossil fuels
carbon that was locked up in these fuels is released
Agriculture
more farm animals produce more methane through their digestive processes
Creating waste
more landfill sites and more waste from agriculture means more CO2 and methane released by decomposition of waste
Carbon dioxide
greenhouse gas
Long wavelengths
________are absorbed by greenhouse gases
Increasing carbon dioxide is
______linked to climate change
Consequences of climate change
ice caps melting, change in rainfall patterns and change in temperature
