Quizplus · Accepted Answer

Scarps, or long lines of cliffs, are a result of the surface of a celestial body cooling and shrinking. They have been observed on Mercury, the Moon, and Rhea (a moon of Saturn), but not on Earth in the context described. Earth's cliffs are primarily formed through different processes, such as erosion and tectonic activity.
