Question
Which of the following gases protect us from the harmful UV rays of the Sun?
- Oxygen
- Nitrogen
- Sulfur dioxide
- Ozone
Hint:
The Earth is the only planet in the solar system that can sustain life. This is mainly because of the blanket of gases that make the atmosphere which provides the air that we breathe and also protects us from the blasts of heat and radiation emanating from the sun. It helps to keep the planet warm during the day and cool at night.
The correct answer is: Ozone
Ozone gases protect us from the harmful UV rays of the Sun.
Ozone is a gas made up of three oxygen atoms that are abundantly found in the atmosphere.
