Final Answer:
What are the greenhouse gases?
— Carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O), water vapor, and others
What do greenhouse gases do?
— Warm the atmosphere by trapping heat
What is the greenhouse effect?
— The warming of the atmosphere because of insulation by greenhouse gases
How does the greenhouse effect work?
— Incoming radiation from the sun reaches the Earth and is absorbed by the greenhouse gases, warming and insulating the Earth like a “blanket”
Is the greenhouse effect a good thing?
— Yes!! Because it maintains a temperature suitable for life
So why is the greenhouse effect considered a bad thing and is linked to global warming?
— Excess of the greenhouse effect is a bad thing. Since there are more and more greenhouse gases in the atmosphere, more heat is trapped which makes the earth warmer. This is called global warming
