The energy debate – Did you know?

The video explains how Earth's surface absorbs sunlight and releases it as heat. Greenhouse gases in the atmosphere, such as carbon dioxide, trap this heat and reflect it back to Earth, causing the planet to warm. The video highlights the significant role of carbon dioxide in increasing Earth's temperature.

What happens to the sunlight when it strikes the Earth's surface?

• It is converted into sound energy.

• It is absorbed by the oceans.

• It is reflected back into space.

• It is absorbed and released as heat energy.

What is the primary function of greenhouse gases in the atmosphere?

• They increase the oxygen levels in the atmosphere.

• They cool down the Earth's surface.

• They trap heat and reflect it back to Earth.

• They absorb sunlight directly.

Which gas is considered the most abundant greenhouse gas?

• Methane

• Nitrous oxide

• Carbon dioxide

• Ozone

How does an increase in carbon dioxide levels affect the planet?

• It makes the planet cooler.

• It has no effect on the planet's temperature.

• It increases the planet's oxygen levels.

• It makes the planet hotter.

What is the relationship between carbon dioxide and global warming?

• More carbon dioxide leads to a cooler planet.

• More carbon dioxide leads to a hotter planet.

• Carbon dioxide has no impact on global warming.

• Carbon dioxide decreases the amount of sunlight reaching Earth.
