Answer:The troposphere is denser then all its overlying atmospheric layers because a larger atmospheric weight sits on top of the troposphere and causes it to be most severely compressed.
The troposphere is denser than all its overlying atmospheric layers because a larger atmospheric weight sits on top of the troposphere and causes it to be most severely compressed. Fifty percent of the total mass of the atmosphere is located in the lower 18,000 ft of the troposphere.
you will see contour elevation numbers. This is the elevation of the contour line, relative to mean sea level. Contour lines that are relatively close together indicate a slope that is fairly steep.
