Question

Quizplus · Accepted Answer

The heterosphere is divided into distinct layers based on the distribution of atmospheric gases. The top layer contains hydrogen and helium, while the bottom layer contains nitrogen and oxygen. These layers are formed due to the differences in molecular weight and gravitational pull on the gases. Therefore, option B is the correct answer.
