Why is most atmospheric mass found in the troposphere?
Answer and explanation
Correct answer: Because gravity keeps air denser near the surface
Earth’s gravity pulls atmospheric gases toward the surface, creating the greatest pressure and density in the lowest layer. Since the troposphere lies next to the surface, it contains most of the atmosphere’s total mass, even though gases also occur above it. Solar heating is not the reason, other layers do contain gases, and the troposphere is not the outermost layer. Option A is correct.
