The statement; “The comet cools down and begins to glow brightly as a result of this decreased temperature.” is considered false. Study shows that comets can be seen because their comas and tails reflect the light from the sun or would usually glow as they absorb energy from the sun. Comets are provided with energy from the Sun , so its movement is always away from the Sun.
The answer is A.
Ice Age or glacial period refers to the extended period of well-below-average temperatures. It is a prolonged period where reduction in the temperature of the Earth’s surface and atmosphere are caused by the expansion of continental and polar ice sheets and alpine glaciers. Usually this phenomenon occurs in the northern and southern hemispheres where extensive ice sheets are seen most.
