  3. Atmospheric Stripping

  4. Atmospheric Depletion
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Atmospheric escape is the process by which a planet loses its atmosphere over time. This can occur due to various factors, such as high temperatures, strong stellar winds, or the lack of a magnetic field.
