The extent of thermal escape in a planetary atmosphere is dependent

Question

Quizplus · Accepted Answer

Thermal escape is the process by which gas molecules escape from a planet's atmosphere into space due to high temperature. The extent of thermal escape depends both on the temperature and molecular weight of the gases in the planet's atmosphere. This means that choice B is the correct answer. The thickness of an atmosphere does play a role in the rate at which gases escape, but it is not the only factor. Molecular weight is also important because lighter gas molecules can escape more easily than heavier ones. Therefore, choice D is incorrect. Neither temperature nor atmosphere thickness alone can fully determine the extent of thermal escape, so choices A and C are incorrect.
