Why are temperatures in the thermosphere not strictly comparable to those experienced near Earth's surface?
What will be an ideal response?
Temperature is defined in terms of the average speed at which molecules move. Because the gases of the thermosphere are moving at very high speeds, the temperature is very high. But the gases are so sparse that, collectively, they possess only an insignificant quantity of heat, whereas the gases near Earth's surface are far more concentrated.
