1.
Multiple Choice
Climate researchers in Greenland can use ice core samples to tell them about methane in the atmosphere in the past. Researchers found a sample that showed a time period when methane in the atmosphere increased. What happened to amount of energy absorbed by Earth's surface during this time?
During this time, the amount of energy absorbed by Earth’s surface
stayed at a constant level.
changed unpredictably.
increased.
decreased.
2.
Multiple Choice
Geologists have found rocks showing that about 700 million years ago, there was a time period when the amount of carbon dioxide in the atmosphere decreased. How did energy in the Earth system change during this time?
There was more energy in the Earth system and more energy absorbed by Earth’s surface, because more energy entered than exited.
There was more energy in the Earth system and more energy absorbed by Earth’s surface, because lessenergy entered than exited.
There was less energy in the Earth system and less energy absorbed by Earth’s surface, because moreenergy entered than exited.
There was less energy in the Earth system and less energy absorbed by Earth’s surface, because less energy entered than exited.
3.
Multiple Choice
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 the atmosphere had less methane?Energy in the Earth system would
decrease, because less energy would enter than exit. This is because less exiting energy would beredirected (bounced) back toward Earth.
decrease, because more energy would enter than exit. This is because less exiting energy would beredirected (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 beredirected (bounced) back toward outer space.
4.
Multiple Choice
Some scientists found that millions of years ago, there was a time when the number of trees increased very quickly, leading to a decrease in the amount of carbon dioxide in the atmosphere. What would you predict about the amount of energy absorbed by Earth's surface during this time?
During this time, the amount of energy absorbed by Earth’s surface
increased.
decreased.
stayed at a consistent level.
changed unpredictably.
5.
Multiple Choice
Scientists have tools that measure the amount of energy entering and exiting the Earth system. Recently, more energy entered the system than exited.
What might scientists expect to see in the atmosphere, and what has changed about energy in the Earth system?
Methane decreased, leading to more energy in the Earth system and more energy absorbed by Earth's surface.
Methane decreased, leading to less energy in the Earth system and less energy absorbed by Earth's surface.
Methane increased, leading to more energy in the Earth system and more energy absorbed by Earth's surface.
Methane increased, leading to less energy in the Earth system and less energy absorbed by Earth's surface.
