How are oxides of nitrogen formed in the air naturally?

Explanation

### Step-by-Step Solution:

1. **Understanding Nitrogen Oxides**: Nitrogen oxides (NOx) refer to a group of gases that include nitric oxide (NO) and nitrogen dioxide (NO2). These gases can be formed through various natural processes.

2. **Natural Sources of Nitrogen Oxides**: One of the primary natural sources of nitrogen oxides is lightning. During thunderstorms, lightning strikes can occur, especially in the rainy season.

3. **High Temperatures from Lightning**: When lightning strikes, it generates extremely high temperatures in the surrounding air. This intense heat can cause the gases present in the atmosphere, particularly nitrogen (N2) and oxygen (O2), to react.
