What are the three main layers of the atmosphere?

The three main layers of the atmosphere are the Troposphere, Stratosphere, and Mesosphere. This correction is significant because understanding the structure of the atmosphere is critical for pilots in relation to weather patterns, altitude considerations, and aircraft performance.

The Troposphere is the layer closest to the Earth's surface, where weather occurs and where almost all of the atmosphere's mass is found. It extends from the Earth's surface up to about 8 to 15 kilometers depending on location, with the highest point generally found at the equator.

Above the Troposphere is the Stratosphere, which extends up to about 50 kilometers above the Earth's surface. This layer contains the ozone layer, which absorbs and scatters ultraviolet solar radiation, and is typically where commercial jet aircraft operate.

Beyond the Stratosphere, the Mesosphere extends to about 85 kilometers. This layer is characterized by decreasing temperatures with altitude and is where meteors burn up upon entering Earth’s atmosphere.

Understanding these layers helps pilots comprehend how weather systems operate, the effects of altitude on flight, and various phenomena related to flying, making this knowledge crucial for safe navigation in aviation.
