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

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?

• 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.

If methane decreased, . . .

• there would be more energy in the Earth system and more energy absorbed by Earth’s surface, because more energy would enter than exit.

• there would be more energy in the Earth system and more energy absorbed by Earth’s surface, because less energy would enter than exit.

• there would be less energy in the Earth system and less energy absorbed by Earth’s surface, because less energy would enter than exit.

• there would be less energy in the Earth system and less energy absorbed by Earth’s surface, because more energy would enter than exit.

What happens when energy hits sulfer dioxide?

• More energy is created.

• Energy gets trapped and is held in the atmosphere.

• Energy gets redirected back towards outer space.

• Energy always passes right through.
