a) every 11 years
b) every 350 days
c) every two million years
d) every 100,000 years

Explanation:

For Question 11: Earth has plate - tectonic activity due to its internal heat and dynamic mantle, while the Moon lacks this. The Moon has a mostly solid interior and no active plate - tectonic system. Earth and the Moon both have had asteroid impacts, and the Moon has had volcanic activity in the past and Earth has a molten core and ongoing volcanic activity.
For Question 12: The sun's magnetic field goes through a cycle of polarity reversal approximately every 11 years as part of its solar cycle.

Answer:

Question 11: D. Plate tectonics
Question 12: A. Every 11 years
