The Earth's atmosphere extends about 62 miles (100 kilometers) above sea level, reaching a boundary known as the Kármán line, which is commonly used to define the edge of space. However, most of the atmosphere, including the majority of weather and breathable air, is concentrated within the first 10 miles (16 kilometers) from the surface. The atmosphere gradually thins out with increasing altitude, transitioning through different layers such as the troposphere, stratosphere, and mesosphere.
