Does the stratosphere layer have air?

The lower boundary of the stratosphere can be as high as 20 km (12 miles or 65,000 feet) near the equator and as low as 7 km (4 miles or 23,000 feet) at the poles in winter. The lower ... Because of this temperature stratification, there is little convection and mixing in the stratosphere, so the layers of air there are quite stable. read more

The percentage is the same but the air ls less dense and, therefore, you need to breathe more of it to get enough oxygen in your blood system. The stratosphere is simply a thermal inversion where the temperature increases with altitude. read more

The stratosphere is a layer of Earth's atmosphere. It is the second layer of the atmosphere as you go upward. The troposphere, the lowest layer, is right below the stratosphere. read more

Diagram of the layers within Earth's atmosphere. Troposphere The troposphere starts at the Earth's surface and extends 8 to 14.5 kilometers high (5 to 9 miles). This part of the atmosphere is the most dense. Almost all weather is in this region. Stratosphere The stratosphere starts just above the troposphere and extends to 50 kilometers (31 miles) high. read more
