The Environment and Sustainability Flashcards

Which of the following best describes the greenhouse effect?

Answer: Trapping of heat by atmospheric gases like CO2 and methane

The greenhouse effect occurs when atmospheric gases trap heat radiating from Earth's surface, warming the planet.

What is deforestation primarily responsible for?

Answer: Loss of biodiversity and habitat destruction

Deforestation destroys habitats and reduces biodiversity while also releasing stored carbon into the atmosphere.

Which renewable energy source harnesses the power of moving water?

Answer: Hydroelectric energy

Hydroelectric energy is generated by capturing the kinetic energy of flowing or falling water.

What does the term 'carbon footprint' measure?

Answer: The total greenhouse gas emissions caused by an individual or activity

A carbon footprint measures the total greenhouse gases, especially CO2, released due to human activities.

Which human activity is the leading cause of air pollution in urban areas?
