The Earth’s atmosphere is a complex, multi-layered system, each layer with unique characteristics and functions. Closest to the surface is the Troposphere, extending up to about 12 kilometers, where weather phenomena occur, and where most of the planet’s air mass resides. Above it lies the Stratosphere, reaching up to 50 kilometers, home to the ozone layer, which absorbs and scatters the sun’s harmful ultraviolet radiation.
The Mesosphere, extending to about 85 kilometers, is where most meteors burn up upon entry. Above this, the Thermosphere ranges from 85 to 600 kilometers.
This layer contains the ionosphere, crucial for radio communication, as it reflects radio waves back to Earth. Finally, the Exosphere, the outermost layer, extends from the thermosphere up to 10,000 kilometers. It’s where the atmosphere thins into space, and satellites orbit the Earth.
Understanding these layers is vital for comprehending various Earth processes, from weather patterns and climate change to satellite technology and space exploration.
