Earth isn’t the only place that “quakes.” Rocky planets and moons regularly experience similar movements, and faults can form between massive chunks of crust on other worlds the same as they can here on Earth. The Moon is one place we know that experiences those kinds of shifts, and new research suggests that it might actually be making the Moon smaller over time.
The study, which was published in Nature Geoscience, explains how the cliffs observed on the Moon’s surface hint at a cooling spell that occurred after the Moon formed. As it cooled, it “shriveled like a raisin,” and large cliffs formed on the surface when the Moon’s crust was compressed. These regions, known as thrust faults, may still be growing today, and the overall size of the Moon may be shrinking as a result.
