Which of the following patterns would you observe if you started at sea level and traveled upward through the Earth's atmosphere to an elevation of 100 km? Choose one or more: A. a progressive decrease in temperature B. decreasing pressure C. changes from warming trends to cooling trends at distinct boundaries D. increasing pressure E. increasing density F. decreasing density

Answer: Option (B) and (F)

Explanation:

Pressure and Density, both are inversely proportional to the height.

The air molecules are mostly present near the surface because of its higher density and the gravitational force that forces them to accumulate near the earth's surface. And as we go up, these air molecules gradually decreases in number and their density also becomes very less, as a result of which the pressure and density both subsequently reduces.

Thus, the correct options are mentioned above, i. e the pressure as well as density both decreases with the increasing height.
