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?

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

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

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

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

A climatologist is creating a simulation for Earth’s climate and is working on how to set it up. One of the options for the simulation is to increase methane in the atmosphere. How should the energy in the Earth system change when the amount of methane in the atmosphere increases?

There should be . . .

• more energy in the Earth system and more energy absorbed by Earth’s surface, because less energy enters than exits.

• more energy in the Earth system and more energy absorbed by Earth’s surface, because more energy enters than exits.

• less energy in the Earth system and less energy absorbed by Earth’s surface, because more energy enters than exits

• less energy in the Earth system and less energy absorbed by Earth’s surface, because less energy enters than exits.

• Nitrogen Dioxide

• Sulfur Dioxide

• Carbon Dioxide

Scientists think that a large amount of carbon dioxide was released from rock on the ocean floor from 120 to 80 million years ago and that this led to increased carbon dioxide in the atmosphere. What happened to energy in the Earth system during this time?

Energy in the Earth system . . .

• increased, because less energy entered than exited. This is because more exiting energy was redirected (bounced) back toward Earth.

• increased, because more energy entered than exited. This is because more exiting energy was redirected (bounced) back toward Earth.

• increased, because more energy entered than exited. This is because more energy was trapped by gases and held in the atmosphere.

• decreased, because less energy entered than exited. This is because more energy from the sun was redirected (bounced) back toward outer space.
