All of the same gases as the troposphere except for a low value of water vapor (mostly because its so cold at the interface). There is also a very small (but very important) amount of ozone and monoatomic oxygen.

The stratosphere mainly contains ozone (O3) gas, which absorbs and scatters incoming ultraviolet (UV) radiation from the sun, protecting life on Earth. It also contains small amounts of other gases such as nitrogen, oxygen, and trace amounts of water vapor.
The main gas found in the stratosphere is ozone. It is present in the form of ozone layer.
The ozone layer is a layer contained in stratosphere. The significant amounts of UV entering the earth are blocked by this. It is a pool of ozone gases.
Yes, the upper stratosphere is generally colder than the lower stratosphere. This is because the stratosphere's temperature increases with altitude due to the absorption of solar radiation by ozone in the lower stratosphere. However, the temperature starts to decrease again in the upper stratosphere due to the cooling effect of gases like ozone and molecular oxygen.
The stratosphere is primarily composed of nitrogen (about 78%) and oxygen (about 21%). It also contains trace amounts of other gases such as ozone, water vapor, and carbon dioxide.
No, most of the ozone in Earth's atmosphere is located in the stratosphere, which is the second layer of the atmosphere. The ionosphere is located much higher in the atmosphere and is composed of ionized gases, not ozone.
