Ozone layer is formed due to reactions of :
a) carbon dioxide and layers of atmosphere
b) oxygen and ultraviolet rays
c) infrared rays and ultraviolet rays
d) cosmic rays and layers of atmosphere
Answer »Answer: (b)
Ozone in the Earth's stratosphere is created by ultraviolet light striking ordinary oxygen molecules containing two oxygen atoms (O2), splitting them into individual oxygen atoms (atomic oxygen).
The atomic oxygen then combines with unbroken O2 to create ozone (O3).
The ozone molecule is unstable and when ultraviolet light hits ozone it splits into a molecule of O2 and an individual atom of oxygen, a continuing process called the ozone-oxygen cycle.
Chemically, this can be described as,
O2 + vuv→ 2O
O + O2 ↔ O3
