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.

A scientist says that even if the amount of energy entering the system from the sun doesn’t change, there can still be less energy entering than exiting the Earth system. What could change in the atmosphere that would cause this and what effect would this have on energy in the Earth system?

• Methane could increase, leading to more energy in the Earth system because more exiting energy would be redirected (bounced) back toward Earth.

• Methane could increase, leading to less energy in the Earth system because more energy from the sun would be redirected (bounced) back toward outer space.

• Methane could decrease, leading to less energy in the Earth system because less exiting energy would be redirected (bounced) back toward Earth.

• Methane could decrease, leading to less energy in the Earth system because less energy would be trapped by gases and held in the atmosphere.

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.

What happens when energy hits sulfur dioxide?

• When energy hits sulfur dioxide, more energy is created.

• Sulfur dioxide traps some energy and holds it in the atmosphere.

• Sulfur dioxide redirects (bounces) some incoming energy from the sun back toward outer space.

• Energy always passes through sulfur dioxide.
