Which planet is losing its atmosphere at faster than the earth?

Correct answer: C. Mars

  • A. Mecury
  • B. Venus

Mars loses atmospheric gas more readily than Earth because its weaker gravity and lack of a strong global magnetic field allow particles to escape into space. Mercury has an extremely thin exosphere, but Mars is the usual comparison in this question.
