I WONDER - What Is The Greenhouse Effect?

The video explains how greenhouse gases, such as carbon dioxide, methane, nitrous oxide, and water vapour, form a blanket around Earth, trapping heat and preventing it from escaping into space. This natural greenhouse effect is crucial for maintaining Earth's temperature at a level that supports life. Without it, the planet would be too cold, with an average temperature of -18°C (0°F) instead of the current 15°C (59°F).

What is the role of greenhouse gases in Earth's atmosphere?

• They allow all heat to escape into space.

• They act like a glass roof, trapping heat.

• They cool down the Earth's surface.

• They block sunlight from reaching Earth.

Which of the following is NOT a greenhouse gas mentioned in the video?

• Nitrous oxide

• Oxygen

• Methane

• Carbon dioxide

How do greenhouse gases affect the Earth's temperature?

• They cause the Earth to overheat.

• They help maintain a warmer temperature.

• They have no effect on temperature.

• They make the Earth colder.

What would Earth's average temperature be without the greenhouse effect?

• 25°C

• 15°C

• 0°C

• -18°C

Why is the natural greenhouse effect crucial for life on Earth?

• It causes extreme weather conditions.

• It prevents all sunlight from reaching Earth.

• It keeps the planet warm enough to support life.

• It reduces the amount of oxygen in the atmosphere.
