Question

Which of these protects the Earth from harmful radiation when found in the stratosphere, but is a pollutant at lower

Answer 1

Answer:

Ozone layer

Explanation:

The ozone layer found in the stratosphere is responsible for protecting the earth against harmful radiation.

In the lower atmosphere, the ozone is a pollutant and very harmful to life.

• Ozone is an oxygen molecule made up of 3 atoms of oxygen covalently bonded to one another.
• It usually found in the ozone layer within the stratosphere just above the reaches of the troposphere.
• Ozone cuts off and absorb harmful ultraviolet rays emanating from the sun.
• This prevents the earth from being exposed to these solar bursts.

Ozone is not found in the air of the troposphere. Here, it will act as a pollutant.

Air is a mixture of many gases of which ozone is not a part of.
