Active Tectonics
The study of structural features within the Earth's crust and their movements, which are caused by the seismic and volcanic activity related to the movement of tectonic plates.
Volcanism
The geological process involving the eruption of molten rock, or magma, from below Earth's surface.
- Ascertain the primary geological activities within our solar system and their consequences.

Final Answer :
C
Explanation :
The main control on whether a planet or moon has active tectonics and volcanism is its size. Larger objects retain heat better, which can drive geological activity, while smaller objects cool faster and are more likely to be geologically inactive.
