Hier is hoe het werkt:

* UV -straling: The sun emits a wide range of electromagnetic radiation, including UV radiation. This high-energy radiation has enough energy to break apart molecules in the thermosphere.

* Photoionization: When UV radiation hits molecules in the thermosphere, it can knock electrons off the atoms, creating ions (atoms with a positive charge). This process is called photoionization.

* Verwarming: The energy from the UV radiation and the kinetic energy of the ions contributes to the high temperatures in the thermosphere.

While the thermosphere is very hot, it's important to note that the density of the gas is extremely low. This means that even though the temperature is high, there aren't enough particles to transfer much heat to anything, including a human. You wouldn't feel hot in the thermosphere, even though it is incredibly hot.
