• during June, July, and August

• during April, May and June

• From June to November

• From November to May

Where is Mauna Loa?

• Near a city in Hawaii

• In a remote location away from cities

• Near an industrial complex

• It is not impacted by a single source of carbon dioxide

• It is impacted by global carbon dioxide changes

• It can measure the changes based on commuting cars in Honohulu

• In can measure the impact of a large factory in Hawaii

What did Keeling's data show?

• It showed the variation of carbon dioxide was irregular

• It proved the amount of carbon dioxide was increasing in a slow speed

• It showed there were seasonal variations of carbon dioxide

What is the cause of seasonal variation of carbon dioxide in Keeling's study?

• Human use more coal in winter rather than summer

• Plants grow in spring and die back in autumn

• Ocean absorb more carbon dioxide in summer

Global average temperature increased rapidly after 1980. What human activity that was considered as the largest relevance to this trend?

• The Renaissance

• Famicom was released in Japan by Nintendo

• Industrial Revolution

The concentration of carbon dioxide dissolved in the ocean is

• Increasing

• Decreasing

• Not changing

• Becoming acidic

What scientist is responsible for measuring CO2 in the atmosphere and showing that CO2 is increasing every year?

• Albert Einstein

• Anthony Davis

• Charles Keeling

• Steven Jobs

The Keeling Curve "curves" upward. Why?

• Because we are in a cooling cycle

• Because earth is getting older

• Because there is all graphs go upward

• Because there is more CO2 in the air each year

How did Charles Keeling get his evidence?

• He drilled in the ice of Antartica

• He captured air in a glass bubble on top of a volcano

• He took samples of soil from volcanoes

• He visited other universities around the world
