What is the most correct result of decreasing atmospheric density with height?
Answer and explanation
Correct answer: Air becomes rarer in upper layers
Atmospheric density is the amount of gas mass contained in a given volume. As height increases, gravity holds fewer air molecules above a location, so pressure and density generally decrease and the air becomes more rarefied. Therefore option A is correct. Soil, rivers, and surface crops are features of the Earth’s lower environment, not consequences of reduced density in upper atmospheric layers.
