Answer 1

All four terrestrial planets, Mercury, Venus, Earth, and Mars, have solid surfaces with signs of geological activity, a characteristic that is common among them.

Step-by-step explanation:

The characteristic that all four terrestrial planets (Mercury, Venus, Earth, and Mars) have in common is that they all have solid surfaces with signs of geological activity on them. While they each evolved differently after their formation from the same solar nebula, they share this fundamental feature. From the massive mountains resulting from volcanism, impact craters dotting their landscapes, to varied levels of current geological activity, all of these planets bear the evidences of their dynamic histories. Not all have thick atmospheres, multiple moons, a rotation period of 24 hours or less, or liquid water on their surfaces. Only Earth still has liquid water on its surface and can support life.
