The Earth's Moon Is <br />Getting Smaller A new study in Nature Geoscience says the astronomical body's crust is wrinkling. The change is caused by cooling on <br />the moon's interior and it not <br />having any tectonic plates. Over time, thousands of cliffs have been produced due to <br />this process. During a span of several hundred million years, <br />the moon is now <br />50 meters slimmer. As shrinking happens, quakes on the moon's faults have occurred. From the late 1960s to the mid-70s, <br />there were nearly 30 of them. The quakes are believed to <br />still be happening. According to Thomas Watters from the <br />Center for Earth and Planetary Studies, <br />the quakes can be powerful.
