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.

Examples of energy forms changing?
solar cells change radiation energy energy into electrical energy solar cells change radiation energy energy into electrical energy solar cells change radiation energy energy into electrical energy
What absorbs X-ray waves?
These are absorbed in the thermosphere and exosphere.
What type of electromagnetic wave does the core of the earth protect us from?
The earth's magnetic field protects us and the earth from things such as solar winds and cosmic particles/radiation as well as solar radiation. Essentially, the magnetic radiation protects us from all harmful waves, varying from infrared rays to gamma rays.
Solar energy travels to the earth in?
Energy from the sun travels to the earth's surface is brought here by electromagnetic radiation. Once the radiation reaches the planet, most of it is converted to heat.
The Earth's magnetic field helps protect living things from?
From solar radiation and cosmic rays
Where does the energy from the thermosphere come from?
Solar radiation
Which two layers of the atmosphere are responsible for the majority of solar radiation absorption?
Stratosphere and Thermosphere
Which two layers of the atmosphere are responsible for the majority of the solar radiation absorption?
Stratosphere and Thermosphere
Why does the temperature in the thermosphere steadily rise?
nitrogen and oxygen atom absorb solar radiation.
Why does the thermosphere have the highest temperature out of all the other layers?
The thermosphere is heated by solar radiation particularly in the far ultraviolet range; much of this is filtered out by the atmosphere's lower layers - but in the these upper regions it is more exposed to this kind of radiation.
What is the layer of the earth's atmosphere ionized by solar radiation?
Not sure about it. But I remembered this layer of the atmosphere called the ionosphere or the thermosphere.
Does solar radiation affect the weather over the entire world?
solar radiation doesnt affect the entire world but it affects awhere the ozone layer has a hole
How does volcanic ash in Earth's atmosphere affect solar radiation?
It increases the amount of solar radiation that is reflected into space
Where and why do auroras occur in earth's atmosphere?
Where: It occurs in the Thermosphere.Why: In the thermosphere, temperature increases steadily as altitude increases because nitrogen and oxygen atoms absorb solar radiation, and so in the ionosphere (the lower region of thermosphere at the altitude of 80 - 400 km) solar radiation that is absorbed by atmospheric gases causes the atoms of gas molecules to lose electrons and to produce ions and free electrons. Interaction between solar radiation and the ionosphere causes the phenomena known as auroras.
Does the thermosphere absorb ultraviolet?
The ozone layer absorbs ultraviolet radiation. The ozone layer is in the stratosphere. So, the thermosphere does not absorb radiation.
The Uppermost atmospheric layer?
The uppermost atmospheric layer is the THERMOSPHERE. here temperature again increases with altitude because many of the gases are absorbing solar radiation.
What is the layer of the atmosphere exposed to the suns radiation?
The Thermosphere
