Question

Which of the following describes air temperature and air pressure at higher altitudes?

(A)Air temperature and air pressure both decrease
(B)Air temperature and air pressure both increase
(C)Air temperature decreases while air pressure increases

Answer 1

Answer:

(A) at high altitudes, both air pressure and temperature decrease.

Answer 2

The correct answer that describes the aspect covered in question is option A: Air temperature and air pressure both decrease.

• As we go to higher heights, the distance from the ground surface grows.
• This ground surface absorbs the most heat during the day and dissipates the most heat at night.
• However, when air molecules are present in the atmosphere, this heat absorption phenomenon occurs.
• The density of air decreases as altitude increases, and the air becomes thinner.
• Air pressure at greater altitudes drops as density decreases.
• Also, because there are fewer air molecules in the atmosphere at greater altitudes, heat is not well absorbed, and the temperature is low.
• As a result, option A accurately represents the situation at a higher height.
