What is Global Warming?

• Increasing temperature in Earth's atmosphere

• Decreasing temperature in a city

• Increasing rain rates in Earth

• Decreasing temperature rates

Without the Greenhouse Effect the Earth would be too

• warm 
• cold
• dead
• funny

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's rotation will slow down and eventually stop

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

Describe the process by which the greenhouse effect occurs

How can global warming cause sea levels to rise? Choose the best answer.

• by causing it to rain more often
• by melting glaciers and ice caps
• by increasing the number of undersea volcanic eruptions
• by creating bigger and more powerful hurricanes

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

Things you can do to help decrease global warming include:

• Eat more ice cream.
• Keep your freezer door open.
• Keep your air conditioner on high.
• Turn off your lights when you’re not using them.

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
