Greenhouse effect

Question 1

where are greenhouse gases found

Answer 1

troposphere

Question 2

how does earth stay in balance

Answer 2

short wave from sun, long wave re-radiated

Question 3

whats greenhouse effect

Answer 3

short wave comes in from sun, long wave gets radiated to space, some gets absorbed by gases and warms planet

Question 4

natural greenhouse effect

Answer 4

essential for life, if no greenhouse effect then planet would be cold, methane/co2/water vapour

Question 5

what gases absorb radiation

Answer 5

water vapour, co2, methane

Question 6

why don’t nitrogen/oxygen absorb radiation

Answer 6

as they have a double bond meaning their stable so dont need to hold onto radiation

Question 7

average surface temperature

Answer 7

15c

Question 8

where do majority of co2 emissions come from

Answer 8

coal/oil/gas, fossil fuels

Question 9

why is human caused greenhouse effect bad

Answer 9

causes global warming

Question 10

impacts of global warming

Answer 10

sea level rise, ocean acidification, precipitation

Question 11

sea level rise

Answer 11

water absorbs radiation which increases temperature and causes thermal expansion (ocean expands), causing flooding

Question 12

ocean acidification

Answer 12

increase of acidity in oceans due to co2 rise, lowers pH, coral bleaching/corrosive to calcium carbonate shells

Question 13

precipitation

Answer 13

more heat in atmosphere means more evaporation so more precipitation/intensity of wind

Question 14

wet/dry areas

Answer 14

wet gets wetter, dry gets drier
