The statement; “The comet cools down and begins to glow brightly as a result of this decreased temperature.” is considered false.

Comets are provided with energy from the Sun , so its movement is always away from the Sun.

the water level of a stream or river exceeds its natural banks, it has reached
its flood stage. This is a real panic stage for people living nearby the rivers

of the area. Most cities and states move their citizens away from the river
banks before it reaches this danger stage. Before the emergence of
technological advancement, historical evidence proves that many great cities
were destroyed due to such situations. <span /></span>
