Climate Change

Which of the following is NOT an effect of Global Warming?

• Polar ice caps will melt.

• Coastal regions will be covered with rising sea levels.

• Some areas will experience serious droughts

• The Earth will experience lower average global temperatures

The main human activity that releases greenhouse gases is

• using bottled water
• burning fossil fuels
• texting on cellphones
• eating meat

Which 2 greenhouse gases contribute the MOST to global warming of Earth?

• N₂O and H₂O

• O₃ and H₂O

• CO₂ and CH₄

• C6H12O6

Why does cutting down trees increase global warming?

• trees soak up carbon dioxide
• trees provide shade which counteracts global warming
• trees absorbs the sun's energy without radiating back into the atmosphere
• trees drain greenhouse gases like methane from soil

The graph below shows CO_2 emissions and temperatures from 1909 to 1949. What conclusion is best supported by the graph?

• There is no relationship between carbon dioxide concentrations and temperatures

• As carbon dioxide concentrations increase, temperatures increase

• As carbon dioxide concentrations increase, temperatures decrease

• As carbon dioxide concentrations decrease, temperatures increase

What is the greenhouse effect?

• A natural process where gases trap heat in the atmosphere.

• A man-made process where gases trap heat in the atmosphere.

• A natural process where the ocean traps heat in the atmosphere.

• A man-made process where the ocean traps heat in the atmosphere.

Which of these is NOT a greenhouse gas?

• Carbon Dioxide

• Nitrous Oxide

• Oxygen Gas

• Methane

This is a simple diagram of the greenhouse effect. According to this diagram, the energy first comes from...

• The Sun

• The Earth

• The Atmosphere

• The Ocean

Which one is NOT a CAUSE of Climate Change?

• Burning Fossil Fuel

• Deforestation

• Intensive Farming / Livestock Gas

• Using renewable resources

In a warmer world, we would expect more
