The question is hard to read, but it sounds like they want to know why the bulb became extinct. I would say disease.
The Thermosphere feels very cold to us because of its low Thermal Energy. There are very few particles in the Thermosphere, so even if they were very, very<span> hot, it would feel cold.</span>
<span>the critical latitude for incoming solar radiation, which could affect the formation of ice sheets is </span>65 degrees N
