Question

What do you understand by greenhouse gases?

Answer 1

• A greenhouse gas is a gas that absorbs and emits infrared radiation.
• They absorb infrared energy (heat energy) emitted from the earth’s surface and reradiate it back to the earth’s surface.
• The greenhouse gases trap heat in the earth’s atmosphere and warm the planet.
• In simple terms, gases that trap heat in the earth’s atmosphere are known as Greenhouse Gases, abbreviated as Greenhouse gases..
• They contribute to the Greenhouse Effect, which is the resultant heating effect.
• Greenhouse Gases Examples:The Primary GHGs are:
• Water Vapour(H₂O), Carbon dioxide(CO₂),Methane(CH₄),Nitrous oxide(NO),Ozone(O₃)
