Question

Define ground level ozone.

Answer 1

Answer:

Ozone is a trace gas of the troposphere, with an average concentration of 20-30 parts per billion by volume, with close to 100 ppbv in polluted areas. Ozone is also an important constituent of the stratosphere, where the ozone layer exists. The troposphere is the lowest layer of the Earth's atmosphere.

Answer 2

Stratosphere ozone, is also known as "ozone layer" forms high in the atmosphere, 6-30 miles above the earth surface, when intense sunlight causes oxygen molecules(O2) to break up and reform as ozone molecules(O3).
