Earth's Changing Climate

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.

Ice core data from Greenland indicates there was a time period on Earth when the atmosphere changed so more energy entered the system than exited. What change to the atmosphere could have caused this and how would it have affected energy on Earth during that time?

• Carbon dioxide increased, leading to more energy in the Earth system because more exiting energy wasredirected (bounced) back toward Earth.

• Carbon dioxide increased, leading to more energy in the Earth system because more energy was trapped by gases and held in the atmosphere.

• Carbon dioxide decreased, leading to less energy in the Earth system because less exiting energy wasredirected (bounced) back toward Earth.

• Carbon dioxide decreased, leading to more energy in the Earth system because less energy from the sun was 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?

• 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.

How do scientists collect evidence about climate?

• Using remote sensing from space satellites.

• By ground based measurements of surface temperature carbon dioxide concentration and sea level.

• . By collecting "proxy data" from tree rings, ice cores and historical records

• All of the above

Which of the following are consequences of climate change?

• Glaciers are shrinking and sea levels are rising

• Heat waves are longer and more intense

• Plant and animal habitat ranges are shifting

• All of the above

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.

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.

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.
