For identifying which layer are gradual merging with space and extremely low gas density the most decisive clues?
Answer and explanation
Correct answer: Exosphere
The exosphere is the outermost atmospheric region and has an extremely low concentration of particles. Its gases are so widely spaced that there is no sharp boundary separating it from outer space; the region gradually transitions into space. Hence option A is correct. The troposphere contains dense air and weather, the stratosphere contains the ozone layer, and the mesosphere is associated with very low temperatures and meteor burning, not the gradual atmospheric escape into space.
