Earth's Changing Climate

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 temperatures go up and down, with no trend.

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

• The graph shows a trend of decreasing temperature over time

6. Using evidence from rocks, scientists have found that from 300 to 290 million years ago, the amount of methane in the atmosphere increased. What happened to the 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.

7. Scientists are using a computer simulation to test ideas about climate on Earth. Looking at one period of time in the simulation, they notice that more energy entered the Earth system than exited. How might the amount of carbon dioxide have changed to cause this, and how would this have changed the energy in the Earth system?
   
   In the simulation,

• carbon dioxide decreased, leading to more energy in the Earth system and more energy absorbed by Earth’s surface.

• carbon dioxide decreased, leading to less energy in the Earth system and less energy absorbed by Earth’s surface.

• carbon dioxide increased, leading to less energy in the Earth system and less energy absorbed by Earth’s surface.

• carbon dioxide increased, leading to more energy in the Earth system and more energy absorbed by Earth’s surface.

1. What would happen in a simulation when you increase the carbon dioxide in the atmosphere. What should the 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.

5. 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.

8. Scientists study tree rings to learn more about Earth’s past climate. They found a time period when the amount of carbon dioxide in the atmosphere decreased. What happened to energy in the Earth system when carbon dioxide in the atmosphere decreased?
   
   Energy in the Earth system

• decreased, because more energy entered than exited. This is because less exiting energy was redirected (bounced) back toward Earth

• decreased, because less energy entered than exited. This is because less exiting energy was redirected (bounced) back toward Earth.

• decreased, because less energy entered than exited. This is because less energy was trapped by gases and held in the atmosphere.

• increased, because more energy entered than exited. This is because less energy from the sun was redirected (bounced) back toward outer space.

If more cotton balls (starting side) go through the barrier than get sent back, what does this represent?

• the receiving side (earth) would get colder

• the starting side (space) would get colder

• the receiving side (earth) would get warmer

• both the receiving (earth) and the staring side (space) would be around the same temperature
