Yläilmoista
Yläilmoista refers to the upper atmosphere, a region of Earth's atmosphere above the troposphere. This vast layer encompasses the stratosphere, mesosphere, thermosphere, and exosphere. The stratosphere, extending from roughly 10 to 50 kilometers above the surface, is known for its ozone layer, which absorbs most of the Sun's harmful ultraviolet radiation. Temperatures in the stratosphere generally increase with altitude due to this absorption.
Above the stratosphere lies the mesosphere, reaching up to about 85 kilometers. This is the coldest part
The uppermost layer is the exosphere, where the atmosphere gradually thins out into outer space. The precise
