Greenhouse gases and Climate change Flashcards
What could an increase in global temperatures lead to?(polar)
Polar ice caps melting-causing a rise in sea level
Increased flooding in coastal area and coastal erosion
What could an increase in global temperatures lead to?(weatyher)
Changes in rainfall patterns-May cause too much or too little water.
Why are green house gases dangerous
They act like an insulating layer in the earths atmosphere-causes the earth to warm up
How can deforestation lead to the greenhouse effect
fewer trees means less CO2 is removed
How does the burning of fossil fuels lead to the greenhouse effect
Carbon that was locked up is released as co2
How can creating waste lead to the greenhouse effect
More landfill sites and more waste from agriculture=more CO2 and Methane
How can agriculture lead to the greenhouse effect?
more farm animals=more methane
What could an increase in global temperatures lead to?(part3)
Frequency and severity of storms may increase
What could an increase in global temperatures lead to?(habitat)
Changes in temperature in areas leading to differences in the habitats of wild species
why is the greenhouse effect necessary for life
It is a natural phenomenon
Without it, earth would be too cold to live on
How have Human activities led to an increase in greenhouse gases
Carbon dioxide-Combustion and deforestation
Methane-increased farming and decomposition of animals
THings you need to know about long wave radiation and greenhouse affect
Greenhouse gases absorb the long wave radiation and they reradiate it in all directions
What is longwave radiation
thermal radiation so it results in the warming up of the surface of the earth
