Climate change quiz

What is climate?

• The weather on a specific day
• The average weather across a large region measured over time
• The weather in a specific location at a specific time

What are the three natural causes of climate change?

• Changes in the earth's orbit, volcanic eruptions, and hurricanes
• Changes in the sun's intensity, earthquakes, and tornadoes
• Changes in the sun's intensity, earth's orbit around the sun, and volcanic eruptions

What effect do volcanic eruptions have on climate?

• They have a warming effect
• They have a cooling effect
• They have no effect on climate

What is the greenhouse effect?

• The cooling of the earth's surface
• The warming of the earth's surface
• Greenhouses gases do not let the Sun rays into earth

What are the main greenhouse gases?

• Carbon dioxide, oxygen, and nitrogen
• Carbon dioxide, methane, and nitrous oxide
• Methane, oxygen, and nitrogen

What causes carbon dioxide emissions?

• Burning fossil fuels, deforestation, and using electricity from fossil fuels
• Using renewable energy

What is the primary source of methane emissions?

• Animal flatulence
• Burning fossil fuels

What is the main consequence of polar ice melting?

• A decrease in sea levels
• A rise in sea levels
• No significant change in sea levels

What are the implications of climate change?

• Increase in plant growth and wildlife
• Increase in rainfall and mild temperatures
• Melting of polar ice, extreme weather events, desertification, and threat to wildlife

What is desertification?

• The cooling of the earth's surface
• The warming of the earth's surface
• No plant/tree growth due to an increase in air temperature, leading to the spread of deserts
