An airplane typically flies in which atmospheric layer?. Mesosphere Troposphere Stratosphere Exosphere

The correct answer is Stratosphere.Airplanes typically fly in the stratosphere, which is the second major layer of the Earth's atmosphere. The stratosphere is located above the troposphere and below the mesosphere. It extends from about 10 to 50 kilometers (6 to 31 miles) above the Earth's surface.The stratosphere is characterized by stable air, low temperatures, and low humidity. It is also where the ozone layer is located, which protects the Earth from harmful ultraviolet radiation. Airplanes fly in the stratosphere because it provides a stable and smooth environment for flight, with minimal turbulence and weather disturbances.The other options are incorrect:- Mesosphere: The mesosphere is the layer above the stratosphere, but airplanes do not typically fly in this layer.- Troposphere: The troposphere is the lowest layer of the atmosphere, where weather occurs. Airplanes do not fly in the troposphere because it is too close to the Earth's surface and is subject to weather disturbances.- Exosphere: The exosphere is the outermost layer of the atmosphere, where the atmosphere gradually transitions into the vacuum of space. Airplanes do not fly in the exosphere because it is too far from the Earth's surface and lacks the necessary atmospheric density for flight.
