In which layer is temperature increasing with increasing altitude?

Question: In which layer is temperature increasing with increasing altitude?

The layer in which temperature increases with increasing altitude is called the "stratosphere." In the Earth's atmosphere, the stratosphere is located above the troposphere and extends from approximately 10 kilometers (6 miles) to 50 kilometers (31 miles) above the Earth's surface.

In the troposphere, which is the lowest layer of the atmosphere where weather occurs, temperature generally decreases with increasing altitude. This is the layer where most of the Earth's weather phenomena, such as clouds, rain, and storms, take place.

However, in the stratosphere, the temperature increases with altitude. This temperature increase is primarily due to the presence of ozone (O3) molecules, which absorb and interact with ultraviolet (UV) radiation from the sun. The absorption of UV radiation by ozone leads to the production of heat, causing the temperature to rise with increasing altitude in this layer.

The stratosphere plays a crucial role in protecting life on Earth, as it contains the ozone layer that absorbs and blocks a significant portion of harmful UV radiation from reaching the surface. The temperature inversion in the stratosphere contributes to this protective function by creating a stable layer where the temperature increases with altitude.
