oxygen absorbs radiation

Question 3

what is a characteristic for the mesosphere?

Answer 3

air is thin

Question 4

what is a characteristic for the stratosphere?

78% nitrogen, 21% oxygen, 1% argon, 1% other

Question 7

what does it mean that the earth is like a greenhouse?

Answer 7

human-made emissions in the atmosphere are trapping heat loss

Question 8

Answer 8

dark places

Question 9

what happens if earth absorbs more solar radiation?

Answer 9

will get hotter

Question 10

where are places on earth that reflect solar radiation?

Answer 10

deserts, ice, clouds

Question 11

what happens if earth reflects more solar radiation?

Answer 11

gets colder

Question 12

why is it important that incoming solar energy equals outgoing solar energy?

Answer 12

so its balanced

Question 13

what are the 5 main GHG’s?

Answer 13

water vapor, methane, nitrious oxide, CFC’s, carbon dioxide

Question 14

where does water vapor come from?

Answer 14

evaporation

Question 15

where does methane come from?

Answer 15

burning fossil fuels

Question 16

where does nitrous oxide come from?

Answer 16

emitted during agricultural

Question 17

where do CFC’s come from?

Answer 17

air thropogenic compounds

Question 18

where does carbon dioxide come from?

Answer 18

natural sources

Question 19

what happens to the climate when there are fewer GHG’s in the atmosphere?

Answer 19

would be cold because there would be nothing to capture the heat near the surface

Question 20

what happens to the climate when there are more GHG’s in the atmosphere?

Answer 20

temperature of earth would increase

Question 21

does mars or venus have more GHG’s?

Answer 21

venus

Question 22

what happens to the climate on venus?

Answer 22

causes the climate to be severely hot

Question 23

how does water vapor act in our atmosphere? (1)

Answer 23

evaporates from the earth’s surface

Question 24

how does water vapor act in our atmosphere? (2)

Answer 24

condenses into the clouds and then either turns into rain or snow

Question 25

how does the carbon cycle go?

Answer 25

1. burning fossil fuels 2. respiration 3. photosynthesis 4. ocean storage of carbon 5. consumption 6. waste 7. burning fossil fuels 8. mining fossil fuels

Question 26

what is one of the largest carbon storage areas?

Answer 26

rocks

Question 27

how is carbon mostly released by humans?

Answer 27

energy production and burning coal

Question 28

what does it matter if the carbon cycle is out of balance?

Answer 28

prevents all of earths carbon from entering the atmosphere

Question 29

what is the most long lived GHG?

Answer 29

carbon dioxide

Question 30

which GHG is released as a result of volcanic activity + burning fossil fuels?

Answer 30

carbon dioxide

Question 31

which GHG is released into the atmosphere as a result of decomposition / agricultural waste?

Answer 31

methane

Question 32

why is venus so hot?

Answer 32

because it had too much atmosphere and the heat cannot escape the planets surface

Question 33

more clouds =

Answer 33

more cooling

Question 34

more rain =

Answer 34

more cooling

Question 35

more water vapor =

Answer 35

more warming
