4.4 Climate Change

Question 1

what are the greenhouse gases?

Answer 1

water vapor, carbon dioxide, methane, nitrous oxides

Question 2

larger impact greenhouse gases

Answer 2

water vapor, co2

Question 3

smaller impact greenhouse gases

Answer 3

methane, nitrous oxides

Question 4

formation of water vapor

Answer 4

evaporation of water bodies

Question 5

formation of co2

Answer 5

cellular respiration, combustion

Question 6

formation of methane

Answer 6

ruminants

Question 7

formation of nitrous oxides

Answer 7

naturally existing nitrogen in soil, car exhaust

Question 8

what is the green house effect

Answer 8

a naturally occurring effect whereby longer wavelength radiation is trapped, allowing heat to be retained in the atmosphere

Question 9

example of short wave length

Answer 9

ultraviolet (UV)

Question 10

example of long wave length

Answer 10

infrared (IR)

Question 11

how do greenhouse gases affect the global temp?

Answer 11

greenhouse gas concentration⬆: heat trapped ⬆

–> global temp ⬆

Question 12

relationship between the industrial revolution and global temp.

Answer 12

industrial revolution: use of machines ⬆ burning of fossil fuels ⬆
–> atmospheric co2 concentration⬆: global temp ⬆

Question 13

There is a _____________ correlation between atmospheric CO2 concentration and global temperature.

Answer 13

positive

–> recent increases in CO2 is largely due to increase in combustion of fossil fuels

Question 14

is ozone depletion one of the causes of enhanced greenhouse effect?

Answer 14

no
