Amplify the Earth's System

From about 120 to 80 million years ago, scientists think that a large amount of carbon dioxide was released from rock on the ocean floor, which 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 wasredirected (bounced) back toward outer space.

A climatologist was working with a computer simulation that models Earth’s climate and atmosphere. She set up the controls of the simulation to decrease the amount of methane in the atmosphere. What should happen to the amount of energy absorbed by Earth’s surface?

When methane decreases, the amount of energy absorbed by Earth’s surface should

• change unpredictably.

• stay at a constant level.

• increase.

• decrease.

Fossil evidence from the time of Tyrannosaurus rex (85–65 million years ago) shows less energy entered the Earth system than exited, even though energy from the sun didn’t change. How might the amount of carbon dioxide changed to cause this, and how would that have changed the energy absorbed by Earth’s surface??

• Carbon dioxide decreased so there was less energy in the Earth system and less energy absorbed by Earth's surface.

• Carbon dioxide decreased so there was more energy in the Earth system and more energy absorbed by Earth's surface.

• Carbon dioxide increased so there was more energy in the Earth system and more energy absorbed by Earth's surface.

• Carbon dioxide increased so there was less energy in the Earth system and less energy absorbed by Earth's surface.

Climate researchers are creating a computer simulation to help them understand changes in the Earth system. They want to use the simulation to see what happens when they increase the carbon dioxide in the atmosphere. What should their simulation show about energy absorbed by Earth’s surface? When carbon dioxide in the atmosphere increases, the amount of energy absorbed by Earth’s surface should . . .

• increase

• decrease

• stay at a constant level

• change unpredictably

The graph above shows global temperature changes between the years 1880 and 2011. Which of the following best describes the changes seen in the graph?

• The graph shows a trend of increasing temperature over time.

• The graph shows the Annual Mean and 5-Year Mean have different trends.

• The graph shows temperatures go up and down, with no trend.

• The graph shows too much fluctuation to be confident about a trend.
