What do you mean by 'Inversion temperature' in different regions of the atmosphere ?

Explanation

**Step-by-Step Solution:**

1. **Understanding the Atmosphere Layers**: The atmosphere is divided into different layers, including the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Each of these layers has a distinct temperature profile.

2. **Temperature Variation with Altitude**: In the troposphere, temperature generally decreases with an increase in altitude. However, in the stratosphere, temperature increases with altitude due to the absorption of ultraviolet radiation by the ozone layer.

3. **Definition of Inversion Temperature**: Inversion temperature refers to a situation where the normal temperature gradient (where temperature decreases with altitude) is reversed. This means that in certain layers of the atmosphere, the temperature increases with height instead of decreasing.
