Question 14

There are some bacteria that release methane into the atmosphere. Scientists think that if the number of these bacteria decreased, the amount of methane in the atmosphere would decrease. What would happen to energy in the Earth system if methane in the atmosphere decreases?

Accepted Answer

decrease, because less energy would enter than exit. This is because less exiting energy would be redirected (bounced) back toward Earth.

Answer

decrease, because more energy would enter than exit. This is because less exiting energy would be redirected (bounced) back toward Earth.

Answer

decrease, because less energy would enter than exit. This is because less energy would be trapped by gases and held in the atmosphere

Answer

increase, because more energy would enter than exit. This is because less energy from the sun would be redirected (bounced) back toward outer space
