Question

Quizplus · Accepted Answer

The craters sitting atop the mare are the youngest visible features on the Moon as they are formed by more recent impacts from meteoroids or asteroids. The other choices are not the youngest visible features as they either formed billions of years ago (volcanoes) or do not have a well-defined age (dark regions of the mare, polar caps, scarps). The craters on top of the mare are the youngest visible features on the Moon, as they were created by impacts that occurred after the mare had formed. The other options are not visible with telescopes or are not the youngest features.
