Greenhouse Effect

In general, what happens to the climate (of the Earth) if more greenhouse gases are released (through human activities and natural occurrences) into the atmosphere?

• Average temperature goes up

• Average temperature goes down

• Average temperature remains the same

• None of the above

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

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 main human activity that releases greenhouse gases is

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

The greenhouse gas having the greatest role in human-caused global warming is

• methane
• carbon dioxide
• CFCs (chlorofluorocarbons)
• ozone

As greenhouse gases increase in the atmosphere....

• More heat gets trapped on Earth which causes warming

• More light gets reflected into space which causes cooling

• More light gets trapped on Earth which causes warming

• More heat gets reflected into space which causes cooling

Check all that apply: Which of the following are consequences of massive deforestation, by burning, of rainforests worldwide?

• Increase carbon emissions into the atmosphere

• Decrease carbon absorption by photosynthesis

• Fewer greenhouse gases in the atmosphere

• Global warming

• Global cooling

In the northern hemisphere, as trees grow new leaves in the spring/summer, what happens to carbon dioxide concentrations in the atmosphere?

• They increase

• They decrease

• They stay constant

The increase in Earth's average temperatures as a result of increased greenhouse gases in the atmosphere is called:

• The greenhouse effect

• Climate change

• Global Warming

• Fantasy

Do we need greenhouse gases on Earth?

• Yes - they keep the Earth warm
• Yes - they keep all the gases on our planet
• No - they only cause terrible climate change
• No - they only block some of the Sun's rays
