GHGS + climate change p2

Question 1

name the 3 greenhouse gases

Answer 1

methane
carbon dioxide
water vapour(nitrous oxide)

Question 2

what is the greenhouse effect

Answer 2

the retention(control) of heat in the atmosphere caused by the build- up of greenhouse gases

Question 3

what are 4 human causes of climate change

Answer 3

industry
farming
transport
energy

Question 4

what is the enhanced green house effect

Answer 4

HUMAN ACTIVITY releases increasing levels of co2 and other greenhouse gases into the atmosphere, increasing the greenhouse effect- more warming

Question 5

how does farming(agriculture) cause cc

Answer 5

global population growth increases demand for food
intensive farmimg(rice)
higher demand for food production

Question 6

how does industry contribute to cc

Answer 6

burning more fossil fuels releases GHGS
rising demand for consumer goods-increase production
disposable income

Question 7

how does transport contribute to cc

Answer 7

more transport relies on fossil fuels(coal)
rising increase in use of transport(car onwership, driving ect)
releases more GHGS in atmosphere

Question 8

how does energy(electricity) contribute to cc

Answer 8

new technologies and population growth increase
demand for electricty produced from fossil fuels
all produce GHGs

Question 9

what is the difference in the natural GHG effect and the enhanced GHG effect

Answer 9

natural-shows more heat energy radiated into to space

enhanced-less heat radiated into space.enhanced for GHGs
