Question

Ozone forms by combination of free oxygen atoms and oxygen molecules. How do free oxygen atoms form at higher levels of atmosphere?
1 point
a) Due to ultra violate rays
b) Due to heat
c) Due to reaction of oxygen and ozone
d) None of the​

Answer 1

Answer:

the answer is (C)

Explanation:

In the stratosphere, ozone is created primarily by ultraviolet radiation. When high-energy ultraviolet rays strike ordinary oxygen molecules (O2), they split the molecule into two single oxygen atoms, known as atomic oxygen. A freed oxygen atom then combines with another oxygen molecule to form a molecule of ozone.

hope it helps u mark me as brainliest and thanks me pls bro

Answer 2

Ozone forms by combination of free oxygen atoms and oxygen molecules. How do free oxygen atoms form at higher levels of atmosphere?

a) Due to ultra violate rays

b) Due to heat

c) Due to reaction of oxygen and ozone

d) None of them

ANSWER:-

• a) Due to ultra violate rays is the correct option.

EXPLANATION:-

• Ozone is to the greatest degree possible present in the stratosphere of the atmosphere. In the atmosphere, the formation of ozone is a constant process because Ultra violet rays have continual action on the molecular oxygen. In the composure of electrical discharges within the atmosphere, the Ultra violet rays with high energy break down and split the oxygen molecule into two freed oxygen atoms.

• The freed oxygen atoms then combine with the molecular oxygen to form an ozone molecule. The formation of Stratospheric ozone is natural through the interaction of solar ultraviolet UV radiation with molecular oxygen.
