Question 1 of 10

Which of the following is the main greenhouse gas contributing to climate change?

Oxygen Incorrect. Oxygen is not a greenhouse gas.

Nitrogen Incorrect. Nitrogen is not a greenhouse gas.

Carbon Dioxide Correct! Carbon dioxide (CO₂) is the primary greenhouse gas contributing to climate change.

Hydrogen Incorrect. Hydrogen is not a greenhouse gas.

Question 2 of 10

What is the primary cause of the increased carbon dioxide in our atmosphere?

Volcanic eruptions Incorrect. While volcanoes do emit CO₂, they contribute much less than human activities.

Burning fossil fuels Correct! Burning fossil fuels like coal, oil, and natural gas is the primary source of human-caused CO₂ emissions.

Plant respiration Incorrect. Plants absorb more CO₂ through photosynthesis than they release through respiration.

Ocean evaporation Incorrect. Ocean evaporation primarily releases water vapor, not carbon dioxide.

Question 3 of 10

Which of the following is NOT an effect of climate change?

Rising sea levels Incorrect. Rising sea levels are a major effect of climate change due to melting ice and thermal expansion of seawater.

More frequent extreme weather events Incorrect. Climate change is increasing the frequency and intensity of extreme weather events like hurricanes, floods, and droughts.

Reduction in earthquakes Correct! Climate change does not affect the frequency or intensity of earthquakes, which are caused by tectonic plate movements.

Changes in plant and animal ranges Incorrect. Many species are shifting their ranges toward the poles or to higher elevations as temperatures rise.

Question 4 of 10

Which of these renewable energy sources currently provides the most electricity worldwide?

Hydropower Correct! Hydropower is currently the largest renewable electricity source globally, though solar and wind are growing rapidly.

Solar power Incorrect. While solar power is growing rapidly, it still provides less electricity globally than hydropower.

Wind power Incorrect. Wind power is growing quickly but still provides less electricity globally than hydropower.

Geothermal power Incorrect. Geothermal power provides a relatively small portion of global renewable electricity.

Question 5 of 10

What is a carbon footprint?

The mark left by carbon paper Incorrect. A carbon footprint is not related to carbon paper.

The total greenhouse gas emissions caused by an individual, event, organization, or product Correct! A carbon footprint measures the total greenhouse gas emissions caused directly and indirectly by a person, organization, event, or product.

The area of land covered by carbon-rich soil Incorrect. A carbon footprint is not a measurement of land area.

The amount of carbon in the atmosphere Incorrect. While related, a carbon footprint specifically measures emissions attributable to a specific source.

Question 6 of 10

Which country was the first to declare a climate emergency?

United States Incorrect. The U.S. followed other nations.

United Kingdom Correct! The UK declared a climate emergency in 2019.

Australia Incorrect. Australia has debated it but not led the declaration.

Canada Incorrect. Canada declared a climate emergency later in 2019.

Question 7 of 10

Which sector contributes the most to global greenhouse gas emissions?

Transportation Incorrect. It's significant but not the largest.

Energy production Correct! Electricity and heat production account for over 25% of global emissions.

Waste management Incorrect. Waste contributes less comparatively.

Agriculture Incorrect. Agriculture is a key contributor but not the top one globally.

Question 8 of 10

Which gas traps the most heat in the atmosphere over a 100-year period?

Methane (CH₄) Correct! Methane traps over 25 times more heat than CO₂ over 100 years.

Carbon Dioxide (CO₂) Incorrect. CO₂ is abundant but less potent per molecule.

Ozone (O₃) Incorrect. Ozone is a greenhouse gas, but methane is more potent long-term.

Nitrous Oxide (N₂O) Incorrect. It's powerful too, but methane is more impactful in 100-year terms.

Question 9 of 10

Which of the following innovations helps remove carbon dioxide from the atmosphere?

Oil refining Incorrect. Oil refining releases more CO₂.

Natural gas flaring Incorrect. Flaring contributes CO₂, not removes it.

Plastic incineration Incorrect. Incineration releases pollutants.

Direct Air Capture (DAC) Correct! DAC uses machines to remove CO₂ directly from the air.

Question 10 of 10

Which international agreement aims to limit global warming below 2°C above pre-industrial levels?

Kyoto Protocol Incorrect. The Kyoto Protocol was a precursor with limited scope.

Paris Agreement Correct! The Paris Agreement, signed in 2015, aims to limit global warming well below 2°C.

Montreal Protocol Incorrect. The Montreal Protocol addresses ozone depletion.

Geneva Accord Incorrect. The Geneva Accord is unrelated to climate goals.
