If a thermometer were placed in the thermosphere, it would register far below 0 degrees C! This may seem strange since the thermospher is so hot.(see answer to "what is one characteristic of each layer of the earth") How can this be explained? Temperatureis a measurement of how fast particles in the air move. The faster the air particles move the higher the temperature. And the particles present in the thermosphere are moving very fast. THerefore the particles themselves are very hot. But these particles are vry few and very far apart. There are not enough of them present to bombard a thermometer and warm it. So the thermometer would re3cord a temperature far below 0 degrees C.
