Question

Quizplus · Accepted Answer

The Tharsis region on Mars having few craters suggests it is the youngest region on the planet. If the region were older, it would have accumulated more impact craters over time. The Tharsis region on Mars has so few craters compared to other regions on the planet, which suggests it is the youngest region on the planet. The lack of craters indicates a relatively recent resurfacing of the area, either through volcanic activity or tectonic processes.
