Students enrolling in Carnegie Mellon University Tepper School of Business have an average GMAT of 690, which is much higher than average compared to all business schools (613).
But how did it end up being this pure in most parts of the Moon? The secondary event that explains it, notes the report, is what researchers are calling a crustal overturn. Old impure plagioclase was replaced by hot, pure plagioclase as the moon cooled rapidly. Asteroid hits, space dust, and other harsh space conditions could have also sheared away the surface impurities, notes the report.

This wide variation is because Earthâs moon has no atmosphere to hold in heat at night or prevent the surface from getting so hot during the day. A single day on the moon lasts about 28 Earth days, meaning the lunar daytime is nearly two Earth weeks long.
