In the thermosphere, ultraviolet (UV) and X-ray radiation from the Sun is absorbed by the sparse gases present, leading to the ionization of these gases. This absorption process significantly increases the temperature of the thermosphere, which can reach up to 2,500 °C (4,500 °F) or higher. The ionization also contributes to the formation of the ionosphere, which plays a crucial role in radio communication and atmospheric phenomena like the auroras. However, the density of the gases is so low that the heat is not felt as it would be at lower altitudes.
What else can I help you with?
If the UV radiation from the sun is absorbed in the thermosphere, what happens to the temperature?
It decreases.
What does the thermosphere protect life on Earth from?
UV rays It is also where the southern aurora's are
How does the Thermosphere help us?
The thermosphere, which is a region of the Earth's atmosphere, is above the mesosphere. The thermosphere helps the planet because it absorbs most of the X-ray and UV radiation from the Sun. The thermosphere extends from 53 miles to about 621 miles above the Earth's surface.
What 2 types of waves do earth telescopes use?
Mainly visual and radio. But there are Xray, UV and IR.
Does the process of photoconduction only occur in the visible light spectrum?
No, it is also observed in case of UV, Xray, Gamma ray.
What are the layers of the atmosphere and what happens in each?
The layers of Earth's atmosphere, from lowest to highest, are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. In the troposphere, weather events like clouds and precipitation occur. The stratosphere contains the ozone layer that absorbs harmful UV radiation. The mesosphere is where most meteorites burn up upon entry. The thermosphere is where auroras happen, and satellites orbit. The exosphere is where the atmosphere merges with space.
What happens to the uv rays aborbed by the ozone?
The UV gets destroyed. It gets converted into energy.
If a UV ray gets into your skin then you put sunscreen what happens to the UV ray?
Nothing will happen. UV rays are reflected after putting sunscreen.
In which layers of the atmosphere does the temperature increase with increasing height?
The stratosphere is where the temperature increases with height. This is due to absorption of UV radiation by atmospheric ozone.
What is siganl bandwidth?

How does the solar radiation affect the thermosphere?
The sun radiates radiation in the UV, visible, and infra-red regions of the spectrum. When this reaches earth, some is reflected off the atmosphere/ clouds back into space. However, some passes through. UV radiation ionises molecules in the thermosphere, and this is the cause of the aurora. Infra-red radiation heats the molecules by giving them more vibrational energy (their bonds vibrate more), and this energy is transferred to other molecules via collisions (kinetic) or re-emitting the IR radiation. Therefore, during the day the thermosphere heats up, which causes it to expand slightly, which is why the height of the top of the thermosphere changes. This also affects the density of the air in the thermosphere.
What is the thermosphere's job in the atmosphere and what would happen if there was no thermosphere?
Thermosphere shields us from radiation that the sun emits. That is its main job. It serves as a protective shield against the x-ray and UV radiation being emitted by the sun and keeps earth's temperature in which living things can survive. Without it, the earth will be destroyed by radiation heat.
