In which layer are pressure and density higher because most atmospheric mass is present?
Answer and explanation
Correct answer: Troposphere
The governing principle is gravity and the weight of the air column. Gravity pulls atmospheric gases toward Earth, so the lowest layer contains the greatest share of atmospheric mass. Consequently, air pressure and density are highest near the surface and decrease upward. The troposphere is therefore correct; the exosphere, thermosphere and mesosphere are progressively higher and much thinner.
