Which is a major source of carbon dioxide from transport?
Answer and explanation
Correct answer: Burning petrol and diesel in vehicles
Petrol and diesel are fossil fuels. Their combustion in vehicle engines oxidizes carbon and releases carbon dioxide, making road transport an important human source of greenhouse-gas emissions. Fish respiration and rock weathering participate in natural cycles, while cloud formation does not produce a comparable direct CO₂ source.
