climate change

Question 1

Greenhouse gases

Answer 1

greenhouse gases absorb and emit long wave (infrared) radiation, thereby trapping and holding heat within the atmosphere

Question 2

greenhouse gasses with the largest warming effect

Answer 2

1) water vapour
2) carbon dioxide

Question 3

two factors that determine the warming impact the greenhouse effect will have

Answer 3

1) ability to absorb long wave length radiation (larger=warmer)
2) concentration within atmosphere (larger=warmer)

Question 4

greenhouse effect

Answer 4

the greenhouse effect is a natural process whereby the atmosphere behaves like a greenhouse to trap and retain heat

Question 5

increasing factors of greenhouse gases

Answer 5

• Deforstation
• increased farming/agriculture
• combusted fossil fuels
• increased reliance on fossil fuels

Question 6

effects of an increased greenhouse gas

Answer 6

• more frequent extreme weather conditions
• areas more drought effected
• changes of circulating ocean currents

Question 7

threats to corral reefs

Answer 7

threats to coral reefs from increasing concentrations of dissolved carbon dioxide
