Actually, the thermosphere has 2 layers of its own called the ionosphere and the . They combine to create a protective sheild that maintains our delicate energy balance essential for life on Earth. High-energy X-rays and UV radiation from the Sun are absorbed in the thermosphere, raising its temperature to hundreds or at times thousands of degrees. The coldest layer of atmosphere is Mesosphere, which is 88 km from stratosphere. The thermosphere (or the upper atmosphere) is the height region above 85 kilometres (53 mi), while the region between the tropopause and the mesopause is the middle atmosphere ( stratosphere and mesosphere) where absorption of solar UV radiation generates the temperature maximum near an altitude of 45 kilometres (28 mi) and causes the ozone layer.

It is made up of the ionosphere and the exosphere. 2 answers: borishaifa [10] 1 year ago. Since it is situated above the thermosphere and in contact with outer space, scientists refer to it as a transit point between the atmosphere and interplanetary space. It can reach temperatures up to 1500 degrees Celsius or more. This layer is mainly composed of extremely low densities of hydrogen, helium and several heavier . The troposphere is the lowest layer and contains about 80% of the total mass of the atmosphere. A further region, beginning about 500 km above the Earth's surface, is called the exosphere. When large magnetosphere storms occur in the thermosphere layer, thermospheric storms are produced. It's a very active part of the atmosphere, and it grows and shrinks depending on the energy it absorbs from the sun. "Air" is the common name given to the combination of gases used by organisms for breathing and photosynthesis. Layers of the atmosphere: troposphere, stratosphere, mesosphere and thermosphere.
