Quizplus · Accepted Answer

Studies have shown that Mercury has a heavily cratered surface, indicating that it has not undergone significant geological activity in the past few billion years. This suggests that its surface is the oldest of the four terrestrial planets. Venus has a younger surface due to volcanic activity, Earth's surface is constantly being reshaped by plate tectonics, and Mars has evidence of geological activity such as volcanic eruptions and canyon formation, indicating a younger surface as well.
