Why can gas molecules in the exosphere possibly escape Earth’s gravitational influence?
Answer and explanation
Correct answer: Because density is very low and collisions between molecules are very rare
Option A is the best answer. The exosphere contains an extremely small number of particles, so its density and collision frequency are very low. A fast, light atom or molecule can therefore travel a long distance without losing much energy in collisions; some may reach escape trajectories. Rainfall, increased heaviness, and ocean moisture do not explain exospheric escape.
