Question

Answer 1

Ozone in the stratosphere is helpful; it absorbs harmful UV-B and UV-C waves from the sun, which are both known to cause sunburn and skin cancer. On the other hand, ozone in the troposphere is very damaging; it is a major component of photochemical smog, and it causes eye, nose, and lung irritation and aggravates asthma.
