![]() ![]() This layer is not suitable for aeroplanes to fly because most meteors burn in this layer which is harmful. Option A – Mesosphere is the layer above the stratosphere which extends up to a height of about 85 km above the ground. ![]() ![]() The layer that exists between the troposphere and the stratosphere is termed as the tropopause.Īlso, large passenger planes cannot fly at higher levels because the air is too thin above that and the oxygen level decreases. Passengers planes mostly fly in the lower stratosphere layer and also in the top level of tropopause because these are less turbulent layers and provide a smoother ride. The sweet spot of flying an aeroplane is regarded to be between 35,000 to 42,000 feet because if the layer is too high, the oxygen level becomes too sparse to fuel the engines and if it is too low, there is greater air resistance. Most of the jet aircraft fly in the lower layer of the stratosphere, to avoid any turbulence, although thunderstorms do penetrate the stratosphere. It usually extends up to 50 km above the ground. Hint: There are six layers in the Earth’s atmosphere and the sweet spot of flying an aeroplane is regarded to be between 35,000 to 42,000 feet.Ĭomplete Step by Step Answer: Stratosphere is the layer of the atmosphere where planes usually fly.
