Detailed explanation-1: -The stratosphere is where you’ll find the very important ozone layer. The ozone layer helps protect us from ultraviolet radiation (UV) from the sun. In fact, the ozone layer absorbs most of the UV radiation the sun sends to us. Life as we know it wouldn’t be possible without this layer of protection.

Detailed explanation-2: -The stratosphere is a layer of the atmosphere that surrounds the Earth. As it absorbs energy from incoming ultraviolet radiation from the Sun, ozone, an uncommon form of oxygen molecule that is relatively abundant in the stratosphere, heats this layer.

Detailed explanation-3: -stratosphere, layer of Earth’s atmosphere lying between the troposphere and the mesosphere. The lower portion of the stratosphere is nearly isothermal (a layer of constant temperature), whereas temperatures in its upper levels increase with altitude.

Detailed explanation-4: -Stratosphere. The Stratosphere extends around 31 miles (50 km) down to anywhere from 4 to 12 miles (6 to 20 km) above the Earth’s surface. This layer holds 19 percent of the atmosphere’s gases but very little water vapor. In this region the temperature increases with height.
