In which layer of the atmosphere do planes fly?
The Earth’s atmosphere is composed of five major layers, each with distinct characteristics. Starting from the Earth’s surface and moving upwards, these layers are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Planes fly in the second layer of the atmosphere, called the stratosphere. Positioned above the troposphere and beneath the mesosphere, the stratosphere derives its name from its temperature stratification, where warmer layers reside at higher altitudes while colder layers hug our planet’s surface.
The correct answer is Stratosphere.
