Question

Do you think Greenhouse Gases affect earth's heat budget? Give examples to support your answer.

Answer 1

Yes, greenhouse gases do affect Earth's heat budget.

They trap heat in the atmosphere by absorbing terrestrial radiation (heat emitted by Earth) and preventing it from escaping into space. This keeps the planet warm enough for life.

Examples:

• Carbon dioxide (CO₂): From burning fossil fuels—major contributor to global warming.

• Methane (CH₄): From agriculture and landfills—more effective at trapping heat than CO₂.

• Water vapour (H₂O): Naturally present—amplifies warming through feedback.

• Nitrous oxide (N₂O): From fertilizers—also a potent greenhouse gas.
