Answer:
The planet known for being covered in 'cliffs and craters' and having a 'weak magnetic field is Mercury'.
Step-by-step explanation:
- Mercury stands as the smallest of all planets in our Solar system. It is magnetically one of the weakest of all planets.
- It is most probably due to its 'proximity' with the Sun, that its surface is full of rising cliffs and craters formed from the volcanic eruptions and also due to the hitting received of extra-planetary objects on it.
