Question

if we removed all greenhouse gasses the

a. earth temperature would stay where it is today
b. the earth temperature would continue to rise
c. the earth temperature would drop to zero degrees
d. the earths rotation would stop
e. 14 billion
f. 20 milion

value: 10

check all the following that are notgreenhouse gasses.
mark all correct answers
a. carbon dioxide
b. oxygen
c. methane
d. nitrogen
e. nitrous oxide
f. all of these are greenhouse gasses

value: 10

what is the function of greenhouse gasses?
a. they increase the release of heat from the earths core to the atmosphere
b. they prevented radiant energy from reaching the earths surface
c. they reflected the suns energy back into outer space.
d. they trap heat in the earths atmosphere
e. they block sun light

Explanation:

• First question: Greenhouse gases trap heat. Removing them would lead to a significant temperature drop. Zero degrees is a rough approximation of the temperature without greenhouse - gas warming.
• Second question: Carbon dioxide (\(CO_2\)), methane (\(CH_4\)), and nitrous oxide (\(N_2O\)) are greenhouse gases. Oxygen (\(O_2\)) and nitrogen (\(N_2\)) are not.
• Third question: The main function of greenhouse gases is to trap heat (infra - red radiation) in the Earth's atmosphere.

Answer:

• First question: c. the earth temperature would drop to zero degrees
• Second question: b. Oxygen, d. Nitrogen
• Third question: d. They trap heat in the earths atmosphere
