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.
The interaction has other important consequences. Over time, the Moon's rotation has become tidally locked, so that the same side of the Moon always faces Earth. And the Moon acts to stabilize a wobble in Earth's axis.Over billions of years, this has led to a much more stable climate, which was friendly to the evolution of life.The Earth-Moon interaction also slows Earth's rotation by about two milliseconds per day per century.nd the Moon acts to stabilize a wobble in Earth's axis.
