▶ Your Answer :
According to the
reading passage, transient lunar phenomena, also called TLPs, are changes in
the color of small areas of the Moon. The reading passage mentioned three
examples of hypotheses about causes of TLPs. However, the lecturer doesn’t
agree with these hypotheses for few reasons. First, the
lecturer explained that cloud of lunar gas is not the cause of TLPs. The
reading passage said that TLPs are mostly seen in the vicinity of craters and
the emission of radon gas was detected near a crater as well. But, the lecturer
argued that it is not known how much radon gas was emitted. Also, the emission
was not big enough to be seen in the Earth. Second, the
lecturer argued that clouds of dust didn’t cause TLPs. To be observed in the
Earth, he argues that the dust storm should be very large. In contrast, recent
studies show that there is no indication of that large amount of dust on the
surface of the Moon. According to a report of astronomer some parts of the moon
are even free of fine dust particles. Lastly, the
lecturer contended that there is no evidence that solar radiation caused TLPs.
When the scientists actually compared the solar cycle with the cycle and
durations of TLPs, scientists found that actually the two more often don’t
consist. So there is no correlation between solar radiation and TLPs. |
