Q: Planetary scientists call the thin gaseous envelope around the Moon as the ––––––.
  • A. lunar stratosphere
  • B. lunar thermoshere
  • C. lunar exosphere
  • D. lunar endosphere
Correct Answer: Option C - Planetary scientists prefer to call the thin gaseous envelope around the Moon as the 'Lunar exosphere' Since it is so tenuous that the gas atoms very rarely collide with each other. while the Earth's atmosphere near the mean sea lavel contains-1019 atoms in a cubic centimeter of volume, the lunar exosphere contains 104 to 106 atoms in a cubic centimeter. Argon-40 which is one of the isotopes of the noble gas is an important constituent of the lunar exosphere.
