What is the role of nitrogen monoxide in depletion of ozone layer?

Explanation

**Step-by-Step Solution:**

1. **Understanding Nitrogen Monoxide**: Nitrogen monoxide (NO) is a type of nitrogen oxide that can be emitted from various sources, including vehicles and industrial processes.

2. **Emission at Ground Level**: When nitrogen monoxide is released into the atmosphere, it is relatively stable at ground level. This means it does not immediately react or cause significant environmental damage when it is near the Earth's surface.

3. **Rising to the Stratosphere**: Over time, nitrogen monoxide can rise into the stratosphere, which is the second layer of the Earth's atmosphere. This layer is important because it contains the ozone layer, which protects the Earth from harmful ultraviolet (UV) radiation.
