Multiple-Choice Questions on Global Warming

What is the primary cause of the narrator's anger toward the listener?

• They disrespected the narrator.

• They contributed to global warming.

• They harmed the narrator's environment.

• They refused to listen to explanations.

What are greenhouse gases?

• Gases found only in greenhouses.

• Gases that contribute to plant growth.

• Gases like carbon dioxide, methane, and nitrous oxide that trap heat.

• Gases that reflect all of the sun's rays into space.

Why are greenhouse gases important in the right quantities?

• They keep the Earth's temperature comfortable for life.

• They block harmful UV rays.

• They prevent all heat from escaping into space.

• They are necessary for plants to grow.

What would happen to the Earth without greenhouse gases?

• It would become uninhabitable due to extreme heat.

• It would freeze with an average temperature of -18°C.

• It would have the same temperature all year round.

• It would be covered in dense fog.

What is the greenhouse effect?

• The process by which plants grow inside greenhouses.

• The process of heat being trapped by gases in the atmosphere to keep Earth warm.

• The reflection of all sunlight by the Earth's surface.

• The cooling effect caused by deforestation.

What is the relationship between deforestation and greenhouse gases?

• Deforestation reduces the absorption of greenhouse gases, increasing their concentration.

• Deforestation directly creates greenhouse gases.

• Deforestation cools the Earth by creating open spaces.

• Deforestation does not affect greenhouse gases.

Why does the Earth's temperature rise due to greenhouse gases?

• The gases trap more heat as their concentration increases.

• The gases prevent sunlight from reaching the Earth.

• The gases reflect all heat into space.

• The gases produce heat themselves.

Which of the following is NOT mentioned as a source of greenhouse gases?

• Factories

• Cars

• Volcanoes

• Deforestation

What role do trees play in the carbon cycle?

• They emit greenhouse gases.

• They absorb carbon dioxide, reducing greenhouse gas levels.

• They produce oxygen that replaces greenhouse gases.

• They reflect sunlight to cool the Earth.

What happens when the layer of greenhouse gases becomes thicker?

• More heat escapes into space.

• More heat is trapped, increasing Earth's temperature.

• Less sunlight reaches the Earth.

• Greenhouse gases stop functioning.
