Ülakihtidel

Ülakihtidel is a term that refers to the upper layers of the Earth's atmosphere. This region is characterized by a significant decrease in temperature as altitude increases, a phenomenon known as an inversion. The upper layers include the stratosphere, mesosphere, and thermosphere. The stratosphere is known for its ozone layer, which absorbs most of the Sun's ultraviolet radiation. Above this lies the mesosphere, where temperatures drop dramatically, making it the coldest region of the Earth's atmosphere. The thermosphere is the outermost layer, where temperatures rise again due to the absorption of high-energy solar radiation, though the air is extremely thin. Phenomena like auroras occur in the thermosphere. Understanding these upper layers is crucial for studying weather patterns, climate change, and the behavior of spacecraft.
