What is the primary source of energy for the Earth's climate system?

• The Moon

• The Sun

• The Earth's core

• Ocean currents

Which of the following is a renewable energy source?

• Coal

• Natural Gas

• Solar Power

• Nuclear Power

Explain why solar panels are more effective in sunny regions compared to cloudy regions.

• They require less maintenance in sunny regions.

• They absorb more sunlight, converting it into more electricity.

• They are cheaper to install in sunny regions.

• They last longer in sunny regions.

Which of the following processes is responsible for the greenhouse effect?

• Photosynthesis

• Reflection of sunlight

• Absorption and re-emission of infrared radiation

• Evaporation of water

Identify the gas that is most responsible for the greenhouse effect.

• Oxygen

• Nitrogen

• Carbon Dioxide

• Hydrogen

Describe how planting trees can help reduce the greenhouse effect.

• Trees produce oxygen which cools the atmosphere.

• Trees absorb carbon dioxide, reducing the amount of greenhouse gases.

• Trees block sunlight, reducing heat.

• Trees increase rainfall, cooling the Earth.

What is the effect of increased levels of carbon dioxide in the atmosphere?

• Decreased global temperatures

• Increased global temperatures

• Increased oxygen levels

• Decreased oxygen levels

Which of the following is a consequence of global warming?

• Decreased sea levels

• Increased ice coverage

• More frequent extreme weather events

• Decreased global temperatures

How does the melting of polar ice caps affect sea levels?

• It decreases sea levels.

• It has no effect on sea levels.

• It increases sea levels.

• It stabilizes sea levels.

Explain why reducing fossil fuel consumption can help mitigate climate change.

• It increases the production of renewable energy.

• It reduces the emission of greenhouse gases.

• It decreases the Earth's temperature directly.

• It increases the Earth's albedo.
