Detailed explanation-1: -The high temperature of a lightning bolt can break the bonds of atmospheric nitrogen molecules. Free nitrogen atoms in the air bond with oxygen in the air to create nitrogen oxides, which dissolve in moisture to form nitrates that are carried to Earth’s surface by precipitation.

Detailed explanation-2: -In general, human activity releases nitrogen into the environment by two main means: combustion of fossil fuels and use of nitrogen-containing fertilizers in agriculture. Both processes increase levels of nitrogen-containing compounds in the atmosphere.

Detailed explanation-3: -During lightning, the atmospheric nitrogen reacts with oxygen present in the atmosphere to form Nitric acid which comes down to the earth with rainwater and reacts with water to form nitrates that are absorbed by plants.
