1. Which of the following gases is primarily responsible for the
greenhouse effect?
A. Nitrogen
B. Oxygen
C. Carbon dioxide
D. Argon
Answer: c) Carbon dioxide
Rationale: Carbon dioxide (CO2) is the main greenhouse gas
contributing to global warming and climate change by trapping heat in
the Earth's atmosphere.
2. Which of the following is a key characteristic of wind power?
A. It is highly polluting
B. It requires a continuous, strong wind to be effective
C. It uses solar panels to generate electricity
D. It generates power without greenhouse gas emissions
Answer: d) It generates power without greenhouse gas emissions
Rationale: Wind power is a clean energy source that generates
electricity without emitting any greenhouse gases, contributing to a
reduction in climate change.
,3. What does a "green roof" on a building help to achieve?
A. Increase energy consumption
B. Improve air quality and insulation
C. Decrease the number of renewable energy sources
D. Create more space for energy equipment
Answer: b) Improve air quality and insulation
Rationale: A green roof, covered with vegetation, improves insulation,
reduces energy use, and helps mitigate urban heat island effects.
4. Which of the following is an example of an energy storage system?
A. Solar panels
B. Wind turbines
C. Battery storage
D. Geothermal heating
Answer: c) Battery storage
Rationale: Battery storage systems store excess energy generated
during low demand periods for later use, helping balance supply and
demand.
5. What is a carbon footprint?
A. The total amount of carbon dioxide produced by human activities
B. The amount of carbon dioxide naturally emitted by the Earth
, C. The number of trees required to offset CO2 emissions
D. The physical footprint left by carbon-rich activities
Answer: a) The total amount of carbon dioxide produced by human
activities
Rationale: A carbon footprint refers to the total emissions of CO2 and
other greenhouse gases caused by human activities, usually measured in
tons per year.
6. Which energy source is typically used in combined heat and power
(CHP) systems?
A. Solar energy
B. Biomass
C. Wind energy
D. Geothermal energy
Answer: b) Biomass
Rationale: Biomass is commonly used in CHP systems, where it is
burned to generate both electricity and heat, improving overall energy
efficiency.
7. What is the principle behind the operation of a tidal power station?
A. The conversion of sunlight into electricity
B. The use of the movement of ocean water to generate energy
C. The use of geothermal heat to generate electricity
greenhouse effect?
A. Nitrogen
B. Oxygen
C. Carbon dioxide
D. Argon
Answer: c) Carbon dioxide
Rationale: Carbon dioxide (CO2) is the main greenhouse gas
contributing to global warming and climate change by trapping heat in
the Earth's atmosphere.
