Question

Quizplus · Accepted Answer

Mercury is the smallest terrestrial planet and has a very weak magnetic field, indicating that it has cooled down significantly since its formation. These factors make it unlikely for Mercury to have any active volcanism, and there is little evidence to suggest that there has been any in the planet’s history. In contrast, Venus and Mars both have evidence of volcanic activity, and Earth is known for its active volcanoes.
