Scientists are trying to reduce the amounts of carbon dioxide and methane that enter the atmosphere. Which statement explains what will most likely happen as a result of these efforts?These efforts will cause Earth’s average temperature to increase.These efforts will decrease the amount of heat that the atmosphere traps.These efforts will reduce the amount of sunlight that reflects off the clouds.These efforts will allow more thermal energy to enter the atmosphere.
Answer
A
These efforts will cause Earth’s average temperature to increase.
B
These efforts will decrease the amount of heat that the atmosphere traps.
C
These efforts will reduce the amount of sunlight that reflects off the clouds.
D
These efforts will allow more thermal energy to enter the atmosphere.
Explanation
Carbon dioxide and methane are greenhouse gases that trap heat in the atmosphere. Reducing the amount entering the atmosphere means less heat will be trapped, so the best answer is “These efforts will decrease the amount of heat that the atmosphere traps.”
