Climate Change Review MFD

What is climate?

• A long period of time. 
• Atmospheric conditions of a place at a particular point in time. 
• Average atmospheric conditions of a place over a long period of time, usually 30 years. 
• Current weather outlook of a place. 

Which of the following is not a greenhouse gas?

• Carbon dioxide
• Methane
• Water vapour
• Nitrogen

The greenhouse effect is beneficial as it helps to sustain life on earth by naturally trapping heat in the atmosphere. 

• False
• True

Which of the following is not a result of climate change?

• change in axial tilt (tilt of Earth on its axis)
• sea level changes
• rising temperatures
• change in precipitation levels

Which of the following are greenhouse gases?

• Carbon dioxide
• Methane
• Water vapor
• All answers are correct

By what amount did carbon dioxide in Earth's atmosphere increase between 1960 and 2000?

• 40 -50 ppm
• 60 -70 ppm
• 110 -120 ppm
• 360 -370 ppm

Fossil Fuels are:

• any gas that absorbs heat
• mixture of gases surrounding Earth
• average weather over time
• made from plant or animal remains

Which fuel source used to generate electricity emits the most carbon dioxide?

• coal
• natural gas
• petroleum

How do fossil fuels affect the greenhouse effect?

• Burning fossil fuels decreases incoming solar radiation
• Burning fossil fuels decreases the amount of heat trapped
• Burning fossil fuels releases carbon dioxide into the atmosphere trapping more heat
• Burning fossil fuels causes less heat to be trapped

Visible light reaches Earth’s surface while infrared light is trapped as heat. Which characteristic of Earth’s atmosphere causes this to happen?

• the hole in the ozone
• the greenhouse effect
• atmospheric pressure
• the inversion layer
